(409 Conflict) in response to MKACTIVITY - ruby-on-rails

We have been having an issue for months now and I cannot find a possible solution.
We have a server X that hosts a webapp. This webapp, among other things, deals with a svn repository hosted in server Y. This server (repository) is reached using WeBDAV through http://Y/svn/repository
The issue is that sometimes and totally random I get following error when trying to create a new folder in the repository or commit a file (it fails basically in operations that require to commit something):
Svn::Error::RaDavRequestFailed: Server sent unexpected return value (409 Conflict) in response to MKACTIVITY request for '/svn/repository/certainPath';
There is another service S that makes requests to the webapp and causes the svn operations and I can tell that this service uses multiple threads (which I believe is somehow causing the problem but not sure about that).
I have searched all over the place but didn't really find anything useful. I know from another friend that they have that issue too and upgrading to svn 1.7 fixed the issue. In my case upgrading to a newer version is not that simple so I prefer to fix the issue and, of course, finally understand what the hell is going on!
Thanks!
Details:
Server X and Y have Snow Leopard
svn version in X is 1.6.17 (r1128011)
apache version in Y I don't know (no access)

"failed to get context" error against real server, works fine with mockserver

Following the ODATA V4 tutorial in step 2: app runs against mockserver, tips are given to run it against a real server. Used the existing index.html as test/mockServer.html and created a new index.html, pointing to ComponentSupport for oninit. Added cors-anywhere and adjusted the manifest. Works well, both mockserver and real.
That was in step 2 and the app worked fine also against a real server. Fast-forward to step 5 and I notice the app fails to load any data when running against a real server. Long story short, the backend is throwing an error, not even "count" together with "top" is accepted. I checked the docs for ODATA, "count" does not seem to be an exclusive option.
Am I fundamentally misunderstanding the way ODATA works? I am especially puzzled by the fact that the mockserver runs fine.
EDIT: created bugreport
As reported in the closing comment of my bugreport, Microsoft has confirmed the issue: "This was due to an error in the version of the OData WebAPI library we were using in the backing service. I have an update with various fixes, including updating to the latest WebAPI library that contains this fix, that I just haven't pushed out to production yet. Let me see when if I can get that deployed."

XCode Server CI Bot Integrate error (Swift)

I am trying to setup a CI server on my Macbook, I have followed the documentation on the apple website up to the point of creating a bot and integrating my build. When I attempt to integrate the build I repeatedly get the following error:
Bot Issue: error. Build Service Error.
Issue: '/Library/Developer/XcodeServer/Integrations/Caches/14a8ea2a72904f1abcecd38b1c02196b' exists and is not an empty directory (-4).
Integration Number: 13.
Integration URL: https://DavidMcQueens-MacBook-Pro-2.local/xcode/bots/BF817C9/integrations
Description: '/Library/Developer/XcodeServer/Integrations/Caches/14a8ea2a72904f1abcecd38b1c02196b' exists and is not an empty directory (-4).
I have manually deleted the folders in this location, as well as changing the permissions incase the server was having issues writing. Each time I run, I receive the same error. Even after I have deleted the folder so it is empty before the integration.
Does anyone have any ideas on how to solve this issue? I have built my iOS application in Swift (which I believe should still work with the CI server)
I am running OSX Server 4.0 and the latest version of XCode.
I followed Apple's documentation for creating bots
Thanks,
EDIT:
After some experimenting and trying different things to see what the issue is, I disabled 2-factor authentication on my GitHub hosting. This appeared to solve the issue, despite the fact that I was generating a specific application key to get around 2-factor. It solved the issue for a small amount of time, and I managed to successfully get the bot to integrate a few times. However it appears to have gone back to its old tricks.
If anyone has any other knowledge on this, or has managed to get it working on their own machines it will be good to know.
So I believe I have solved this issue, the GitHub 2-factor authentication issue looks to be a red herring.
When setting up the bot, there is a section that says "Checkout the repository", I did not do this step because I already had the repository on my local machine and presumed that it would simply create the repository in another location, and server no other purpose.
However, after some investigation this step is very necessary. From what I understand, checking out the repository does create it again in another location, however this is necessary as this new repository is where the Bot's will pull changes into and build in order to perform the tests. I was trying to use the same repo for development and for the Bots, which it did not like.
Creating a clean checkout of the project (on the server), and configuring the bots in that project then allowed me to progress and get everything setup correctly. It comes down to user error. In hindsight, it makes perfect sense to have a separate repo for the bots (this is my first CI server setup), however the error messages were not helpful and I can't remember seeing this emphasised in the setup guide.

Umbraco Site Publishing

I am using umbraco v 4.11.6 (Assembly version: 1.0.4834.19775) the issue is every time the server shuts down or restarts I need to republish the pages which are not loaded.
So please let me know the root cause for this issue if anyone knows or any other things that can be done to over come from this
Thanks in Advance
In version 4.6 there was an issue which had the same behavior when the SQL database was not available at boot time of the website. But with version 4.11 this should be fixed a long time.
I would investigate the logs (~/app_data/logs/). You might find some clue there. Append logs to your post if you can not find the issue.
This might be a problem with some ApplicationEventHandlers not running properly. Or with write permissions on the proper folders. Try adding more logs to the code, so you are sure what runs (and what doesn't).
If you can not find the answer, try the umbraco forums : http://our.umbraco.org/forum

Repeated "java.lang.IllegalStateException: Cannot forward after response has been committed" errors with Grails and Tomcat

Please see my post on the Grails user mailing list. Essentially, I get the error "Cannot forward after response has been committed" with Grails 2.x after every few requests. This happens for all types of URLs, controllers, GSPs, CSS files, JS files and even image files. I have tried Grails 2.0.0 and Grails 2.0.1 with Tomcat 6.0.35 and Tomcat 7.0.25 on Windows XP 32-bit, Windows 7 32-bit and Centos 64-bit. The error comes up on all these combinations.
As I have mentioned in my post, there are no response.redirect or response.forward statements in our code. This is causing severe problem on our production application so need help in determining what else can be looked at to get to the bottom of the problem.
This has been solved. In one of the controllers in the application, response output stream was being directly written to but not closed explicitly after the operation was over. It seems Tomcat and Jetty recycle response objects. When a response object that did not have their output stream closed earlier was recycled for a future request and redirect was performed on it, the redirect would fail.
The code has been changed and the error has disappeared now. The lesson learned is that any time such an error occurs, scan the entire code base for direct access to response output stream and close output stream responsibly before existing controller methods.
You should create a new grails application and move the controllers, domains and etc yourself rather than grails update.
When you do that also make sure you look into the configuration files of grails.
Also take a look at what plugins you have.
Also, when moving the files, try out the application once in a while when it is possible, and perhaps you can detect when the error arises. Start out by trying it in your most basic controller and see if the error is there then as well.
Good luck.

cookies using Delphi 2010 and Indy

I'm new to dealing with cookies and not sure if my code or maybe Indy version is the problem based on researching other posts.
Using Delphi 2010 and Indy 10.5.5.
Have set up a cookiemanager at design time. I can send an initial login request (using the POST method) to the server that is successful (get a "success" code back from the server app) and the cookie manager shows that it has accepted a cookie from the server.
When I try to reply to the server (again using POST) to get the next set of information, I get an error code back from the server app which indicates an authorization failure and I'm being told by the server tech support people to check the cookie being sent with the reply.
How can I check the contents of the cookie header that is being sent back to the server?
Also, in another post I saw that Indy 10 IdCookieManager.pas and IdCookie.pas have been updated in 2011. Should I update my Indy to the latest version as this might be my problem?
Thanks in advance.
Here is some more info:
Thank you for your previous assistance; I appear to be getting closer to reinstalling Indy10.
I purged my system of all Indy stuff except the most recent version (10.5.8) which I downloaded yesterday. [Actually I just moved the old stuff into a directory with an unusual name.]
Now I get a clean compile on all 5 packages.
I was able to add the two main packages (the ones starting with dcl) to my program's project list.
But I get "[DCC Fatal Error] E2202 Required Package IndyCore not found." when I try to compile my main program.
I tried removing and reinstalling the dcl packages to my project. When I removed them, I got the message that IndyCore and 3 other packages would also be removed - so it seems to know that dclIndyCode140 uses IndyCore140.
I've added some directories to my search path and tried placing the 5 bpl's in different directories. None of that had any effect and at this point I am stumped.
Ideas? Suggestions?
Steve
Upgrading to the latest release is definate recommended. Links are on Indy`s website. Yes, cookie support was broken in earlier Indy 10 releases but it working again now.
As for your other question, to see what TIdHTTP is sending, you have a few choices:
Look at the TIdHTTP.Request.RawHeaders property after sending a request.
Attach one of Indy's TIdLog... components to TIdHTTP, such as TIdLogFile, and look at the output.
Use an external packet sniffer, such as Wireshark.
