JENKINS: After jenkins version updation, job is not starting - jenkins

I am using docker to run my Jenkins instance.
The version which we are using was 2.121. Since last Saturday after the container restart, all my pipeline got vanished. After several hit and trial, when I updgraded to version 1.121.1. All my job got visible again. But when I tried to run any jobs. It is not getting started, after clicking on the build button nothing is happening.
What should I do? any suggestion would be helpful. Thanks

Jenkins: How to disable DockerContainerWatchdog from running

I've installed Docker plugin and was able to setup a test job to run on a slave container.
The test job is a basic loop with echo that runs for 15 minutes.
My problem is that the job never finishes. It runs for a few minutes and then the connection to the slave docker is lost and job gets stuck and fails.
After reading about this issue, I tried several suggested solutions, but it didn't help.
One of the things that can affect my issue is disabling DockerContainerWatchdog from running.
My problem is that I can't figure out how to disable DockerContainerWatchdog from running.
Any help will be greatly appreciated.
Thanks,
Boris.
Got it!
Run the following code in Jenkins' Script Console:
System.setProperty("com.nirima.jenkins.plugins.docker.DockerContainerWatchdog.enabled", "false")
Please note: This will be active only until Jenkins' next restart.

Jenkins job pauses for 15 minutes

I have a job running on a WindowsServer2012R2 agent. The job is pausing between 2 plugins (BuildNameSetter v1.6.8 and DiscardOldBuilds v1.0.5) as you can see below:
13:05:25 Set build name.
13:05:25 New build name is '5.0.811.0'
13:20:21 Discard old builds...
I've started to notice this strange behavior after upgrading Jenkins Master from 2.89 to 2.190.3.
It's frustrating to see your job taking a 15 minutes nap!
Is this a server side issue or a agent side one?
Can someone give me some hints about how to tackle this problem?
Did you experience something similar?
you could have a look at jenkins central logs /log/all to see if there is any java stacktrace error in there
Then you should first try to isolate the issue. try deactivating the build name setter step first. then try to disable the discard old build. then enable build name setter again and keep discard old build deactivated
now you know which plugin is causing the issue try to downgrade or upgrade the plugin that makes your build hang
if the issue comes from discard old build, I would try to remove clean the job's workspace and remove builds manually
look for your issue on jenkins's jira system, upvote. create a ticket if you have not found another user experiencing the same issue
Finally you should be able to find workarounds for these plugins
Today I've upgraded Jenkins to a newer version (2.263.2) on the Jenkins server and the 15 minutes pause dissapeared.

Jenkins BUILD now issue

In the jenkins applications ,I accidentally clicked on the " Build Now " instead of "Build with Parameters" link while trying to Build the application and now its stuck . I am unable to cancel this Build. I tried building the application again however I am unable to promote my new build because the previous Build is still not complete. Is there any way I can abort the previous build ?
in Jenkins Script console (/jenkins/script) try:
Jenkins.getInstance().getItemByFullName(jobName,Job.class).getBuildByNumber(jobNumber).doStop()
Check if you are logged in and you have permissions for aborting the build (should be at job's configuration page)
Jenkins could need some time to process the abortion request.
If you notice that Jenkins is definitely stacked, check the reason.
It could be memory, CPU or space issue.
These Linux commands are highly recommended:
top
df -h
The last and the most unpleasant way is rebooting Jenkins and starting the new job. NEVER try that on production machine :)

Jenkins docker-plugin - Job does not start (waiting for executor)

I'm trying not (not hard enough it seems) to get our jenkins server to provision a jenkins-slave using docker.
I have installed the Docker-plugin and configured it according to the description on the page. I have also tested the connectivity and at least this part works.
I have also configured 1 label in the plugin and in my job. I even get a nice page showing me the connected jobs for this slave.
When I then try to start a build nothing really happens. A build is scheduled, but never started - (pending—Waiting for next available executor).
From the message it would seem like jenkins is not able to start the slave via docker....
I'm using docker 1.6.2 and the plugin is 0.10.1.
Any clue to what is going on would be much appreciated!
It seems the problem was that I had added the docker version in the plugin config. That is apparently a no-go according to this post

Jenkins slaves go offline or hang when archiving artifacts

In the job post build action, am archiving the artifacts. 90% of the time, when the jenkins job reaches this step, the slave on which it is running hangs (or) goes offline (or) the job hangs and if I kill the job it throws a "Caused by: java.lang.OutOfMemoryError: Java heap space" error.
Am running Jenkins ver 1.560.
Has anyone seen this or is aware of a fix for this? Any help is appreciated.
Thanks
It looks like you're running into https://issues.jenkins-ci.org/browse/JENKINS-22734 which started in version 1.560 and will be fixed in 1.563.
It's always a good idea to browse the Jenkins change log, especially the Community Ratings section, when you install a new version.
Whenever Hudson master will run out of space, slaves will disconnect and will have to be restarted.
You need to check Hudson master box and see how much space is allocated to the drive where hudson is running.
Another thing to note is that even if a job is running on slave, artifacts are archived always on master. So space allocation on master should be done properly.
I ran into this issue with 1.560v of Jenkins. Right now I have disabled the archiving of the maven artifacts from the "Build" section.
