      Description

      We've noticed very high cpu usage on the jenkins slave process when running with artifactory.

      Taking an example, I've used the native top program (showing the top threads) and correlated the top threads with the jstack of the slave process and found the troublesome java threads are :

      This high cpu usage can cause jobs to timeout.

      Is therte a way to resolve this ?
