Jobs stuck in a queue for a long time - loggers list needed?

[Jakov Sosic]

Hi guys,

I've been dealing with this problem for some time now. Jobs seem to get
stuck in the jenkins queue, although there are free executors on slaves.

Master connects to slaves via SSH.

I run 3 static slaves with 3 x 100 executors.


So far, only thing that really helps is restart of the jenkins service,
but, it helps only for day or two when the problem reoccurs.


I was thinking of turning on additional logs:

https://wiki.jenkins-ci.org/display/JENKINS/Logging

but I can't find the list of the available loggers...




I'm running:

# cat /etc/redhat-release
CentOS Linux release 7.3.1611 (Core)

# java -version
java version "1.7.0_121"
OpenJDK Runtime Environment (rhel-2.6.8.0.el7_3-x86_64 u121-b00)
OpenJDK 64-Bit Server VM (build 24.121-b00, mixed mode)

# rpm -q jenkins
jenkins-2.32.1-1.1.noarch

# grep ^JENKINS_JAVA_OPTIONS /etc/sysconfig/jenkins
JENKINS_JAVA_OPTIONS="-Djava.awt.headless=true -Xmx8g -XX:PermSize=1024m
-XX:MaxPermSize=1024m -XX:+UseG1GC -XX:+PrintGCDetails

-XX:+UseGCLogFileRotation -XX:NumberOfGCLogFiles=10

-XX:HeapDumpPath=/var/lib/jenkins/heapdump.hprof

-Dhudson.model.ParametersAction.keepUndefinedParameters=true"



Any ideas ?
