I have an issue when starting Jenkins. The Jenkins instance has been in use
for a few months but after installing a recent Jenkins, the instance hangs
on restart. This hang only happens with the --daemon startup option and
oddly, does not occur if I use the same params but omit the --daemon param.
This works but the equivalent --daemon startup fails:
usr/bin/java -Xmx10g -Xms5g -DJENKINS_HOME=/data/jenkins -jar
/usr/lib/jenkins/jenkins.war --logfile=/var/log/jenkins/jenkins.log
--webroot=/var/cache/jenkins/war --httpPort=9000 --ajp13Port=-1 --debug=9
--handlerCountMax=100 --handlerCountMaxIdle=20 --prefix=/jenkins-cl
The hang occurs here (this locks out all other extensions):
"UpdateCenter.init" #101 daemon prio=5 os_prio=0 tid=0x00007f71f8001800
nid=0x2f6a runnable [0x00007f747aeeb000]

I've tried enabling fine debug logging (--debug=9) and tried other
strategies based on https://wiki.jenkins-ci.org/display/JENKINS/Logging but
so far, I can't get the fine logs to appear in my log file (--logfile
option above).
Would anyone have any advice on how to get fine logs from
jenkins.diagnosis.HsErrPidList? Or is there a way to disable this
diagnostic? I suspect that there is a file permissions issue or something
like that.
Any help would be appreciated.
