can anyone help me out in interpreting this panic crash log?
this happens during rotation with many images ... it involves javascript if that is of any help.

Thanks for any insight.
You should use instruments to check memory allocations and memory leaks. It could also be that the app was too long unresponsive and was killed, the text 4 waiters stuck for 12 secs could indicate that. The crash report content and format is pretty unique, haven't seen that one yet. So these are just guesses.

Some versions of BlueStore were susceptible to BlueFS log growing extremely large - beyond the point of making booting OSD impossible. This state is indicated by booting that takes very long and fails in _replay function.
This can be fixed by::
ceph-bluestore-tool fsck –path osd path –bluefs_replay_recovery=true
It is advised to first check if rescue process would be successful::
ceph-bluestore-tool fsck –path osd path –bluefs_replay_recovery=true –bluefs_replay_recovery_disable_compact=true
If above fsck is successful fix procedure can be applied

I have a location service based tracking and geofencing app which would run for days and weeks in the background on and iOS 12.2 ff device.
Now with iOS 13.2 the app gets terminated after a variable amount of time, but at least several hours, due to excessive cpu usage:

While in background the app does nothing more than to write each location update to a sqlite database and checking the current location against a safety perimeter.
There is no reason to assume that the app suddenly after several hours would require such a high cpu usage.
I have not the slightest idea how to approach the problem and I am not even sure if I can do anything about it or if it is a bug in 13.2 and I have to wait for a fix.
My first assumption was, that the old iOS 12.0 bug which terminated background apps without reason and which was fixed in 12.2 was back. But that here seems to be something new. I was able to run the test app iOS 12 terminates apps in the background for no reason for several days.
Any hint how to interprete the log and take action ?
Edit:
It seems, that this is related to iOS 13.2 message: nehelper sent invalid result code [1] for Wi-Fi information request
Location service queries the WiFi interface in second intervals. Instrument shows that these query calls have a memory leak.
Turning off WiFi on the device seems to solve the problem, though that is no true solution. Now waiting for iOS 13.3 to leave beta.
It turned out, that a third party framework that I am using launches calls to CNCopyNetworkInfo in second intervals. These calls could not fullfilled as my App had no WiFi capabilities enabled and thus the calls to CNCopyNetworkInfo caused small memory leaks that added up over time.
After enabling WiFi access capabilities the memory leaks vanished.
I've written a simulator, which is distributed over two hosts. When I launch a few thousand processes, after about 10 minutes and half a million events written, my main Erlang (OTP v22) virtual machine crashes with this message:
no next heap size found: 18446744071789822643, offset 0.
It's always that same number - 18446744071789822643.
Because my server is very capable, the crash dump is also huge and I can't view it on my headless server (no WX installed).
Are there any tips on what I can look at?
What would be the first things I can try out to debug this issue?
First, see what memory() says:
> memory().
[{total,18480016},
{processes,4615512},
{processes_used,4614480},
{system,13864504},
{atom,331273},
{atom_used,306525},
{binary,47632},
{code,5625561},
{ets,438056}]
Check which one is growing - processes, binary, ets?
If it's processes, try typing i(). in the Erlang shell while the processes are running. You'll see something like:
Pid Initial Call Heap Reds Msgs
Registered Current Function Stack
<0.0.0> otp_ring0:start/2 233 1263 0
init init:loop/1 2
<0.1.0> erts_code_purger:start/0 233 44 0
erts_code_purger erts_code_purger:wait_for_request 0
<0.2.0> erts_literal_area_collector:start 233 9 0
erts_literal_area_collector:msg_l 5
<0.3.0> erts_dirty_process_signal_handler 233 128 0
erts_dirty_process_signal_handler 2
<0.4.0> erts_dirty_process_signal_handler 233 9 0

<0.5.0> erts_dirty_process_signal_handler 233 9 0
erts_dirty_process_signal_handler 2
<0.8.0> erlang:apply/2 6772 238183 0
erl_prim_loader erl_prim_loader:loop/3 5
Look for a process with a very big heap, and that's where you'd start looking for a memory leak.
(If you weren't running headless, I'd suggest starting Observer with observer:start(), and look at what's happening in the Erlang node.)
I created a new swift project, and changed nothing to the project. It is just an empty swift project. If I choose to run on iPhone 6, the springboard will crash. But if I choose others (like iPhone 5s or resizeable iPhone, even iPhone 6 Plus), the empty project works fine.
Does anyone know what's wrong with my xcode? And how should I deal with this problem?
The error message was so long that I cannot attach the whole message here. I'll choose some part that seems important to me.

The problem was solved automatically after I update my Xcode into the latest version.
If you have a possible answer for the question, you are still welcomed to answer the question.
I am currently using Xcode 5 on my Macbook Pro which is running OSX Yosemite. I am trying to create an outlet from a UIWebview to a header file. When I let go of my mouse to create the connection, Xcode freezes and crashes. This is repeatedly happening no matter what I have done. I have tried restarting Xcode and my Macbook. Does anyone else have this problem or know how to fix it? Thanks!
I have added the logs from the crash(I couldn't include the backtrace because it exceeded the maximum characters in the body)

I think you should declare a IBOutlet in your header file. And then in Storyboard you try to connect the header file.
Have you ever tried to clean your product(Product->Clean)?
Then, open the xib file as source code and delete your IBOutlet info. Maybe XCode get confused about your IBOutlet.
