SCM/JIRA link daemon commented on JENKINS-6651: ----------------------------------------------- Code changed in jenkins User: Kohsuke Kawaguchi Path: core/src/main/java/hudson/security/PAMSecurityRealm.java http://jenkins-ci.org/commit/pam-auth-plugin/8c9db12f57587d604073f5e9523a539d023a7be4 Log: [JENKINS-6651] inserting artificial lock in the hope that this will eliminate libpam crash. Originally-Committed-As: 86ec2a30f646d90aa4bbe91e3d4937e5661c409e > 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 > Attachments: backtrace-2010-04-12.gz, backtrace-2010-04-19.gz, > backtrace-2010-04-19.gz, backtrace-2010-05-28.gz, > hudson.log.backtrace-2010-06-09_1.gz, hudson.log.backtrace-2010-06-09_2.gz, > Update_Center__Hudson_.pdf > > > 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. -- This message is automatically generated by JIRA.
