Since the restart, it is behaving much better. If your Jenkins instance
is on the same host, it is possible that some of your build performance
was negatively affected during that time.

any idea why it was doing that ?

Maybe if this happens again try to capture some thread dumps of those java processes.
This could help to find out what could be the reason.

looks like you were witnessing several concurrent JGit verification builds each running JGit unit
tests. For several of the changes in the seriesĀ a build was started
but didn't come back reporting a result. You probably killed them when seeing the overloaded server.

Looks like we should reduce the number of executors, I reduced it from 3 to 2 for the JGit JIPP.
