> Hudson crashes for unknown reasons
> ----------------------------------

> Key: JENKINS-6651
> URL: https://issues.jenkins-ci.org/browse/JENKINS-6651
> Project: Jenkins
> Issue Type: Bug
> Components: core
> Affects Versions: current
> Environment: Ubuntu 8.10, 4x 3.2 GHz Xeon, 4 GB RAM, sun-java6-jdk-u20
> Reporter: paalnilsen
> Priority: Critical

> This has happened a couple of times before. Hudson just seems to crash
> without any comprehensible evidence in the log. There is a backtrace and
> mem-map, but I am not a developer so I don't quite understand exactly what is
> going on. I am hoping you have some ideas.
> I see some references to libpam-ldap.so. We are not using LDAP directly in
> Hudson, but authenticating via the Unix user database. Ubuntu then does the
> LDAP auth. All this is working flawless, and the crashes seem very random.
> There are not many people logging in and out of Hudson. Users are me + six
> developers.
> There is the Master server and four slaves. The slaves can build maximum two
> jobs each simultaneously. They are all using Ubuntu + one Fedora, and have
> about the same specs. Everything connected through Dell enterprise class
> switches with gigabit copper.
> Let me know if you need more information. List of installed plugins (all
> latest version as of Hudson 1.359) and the last 5000 lines from three logs
> attached.
