We got an 30 minute free CloudBees support. It was too short to dig deeper
to find the problem, but the person I was talking to (after examining our
logs) mentioned what he thought was the problem and gave a suggestion.
We should not use Jenkins master at all for builds (allocated with the
node("master") step). We had 15 Executors for Jenkins master.
We could also try to Increase limits of hard nofile and nproc for jenkins
user, but the main recomondation was to remove all Executors for Jenkins
master.
> /etc/security/limits.conf
jenkins soft core unlimited
jenkins hard core unlimited
jenkins soft fsize unlimited
jenkins hard fsize unlimited
jenkins soft nofile 4096
jenkins hard nofile 10240 #Was 8192
jenkins soft nproc 30654
jenkins hard nproc 60654 #Was 30654
To remove Jenkins master Executors will take some time. We use Jenkins
master when we publish our build artifacts RPMs to our NFS file storage.
Since our RPM NFS is only attached to the Jenkins master it is not possible
at the moment. Unless we can use any other agent, then do a SCP onto our
Jenkins master with the RPM artifacts.
We had a few other circumstances where we used Jenkins master. Like
checking out a file to determine which build agent to actually use. These I
have already changed to use any available build agent instead.
