Ed Palazzo commented on JENKINS-13827:
--------------------------------------
We continue to have this problem with OutOfMemory Exceptions. It happened again
last night, which is about right... every one to two weeks.
Has anyone had a chance to look at the heap dump?
Thanks in advance.

> Getting OutOfMemoryError after Jenkins has been running for several days

> Key: JENKINS-13827
> URL: https://issues.jenkins-ci.org/browse/JENKINS-13827
> Project: Jenkins
> Issue Type: Bug
> Components: core
> Environment: Jenkins 1.458
> Red Hat Enterprise Linux ES release 4 (Nahant Update 4)
> 32-bit hardware and OS
> java 1.6.0_17
> perforce plugin 1.3.8
> 8 virtual CPUs
> 16 GB total available memory on the system
> Reporter: Ed Palazzo
>
> After running from anywhere from one to two weeks, Jenkins will appear to be
> frozen. Examination of the logs shows the following error:
> java.lang.OutOfMemoryError: GC overhead limit exceeded
> I've done numerous stack dumps, and it is fairly inconsistent as to what is
> happening when the error occurs. This last time I did a heap dump per the
> instructions on this page:
> https://wiki.jenkins-ci.org/display/JENKINS/I%27m+getting+OutOfMemoryError
> The heap is available for download via FTP here:
> ftp://Jenkins:maqla...@kpsg.kofax.com/heap.bin.gz
> It's about 300M compressed (~1.6GB uncompressed). I had a hard time running
> jhat against the heap -- maybe you'll have more luck.
> I should let you know that I have 565 jobs (all modules of different
> branches) configured on this system. I have one slave running builds, with
> another two machines on the way.
> Let me know what else I can provide to help debug.
