      Hello,

      We have been using Jenkins integrated with Bitbucket Cloud to build pull request. 

      Starting from July 22, our Jenkins crash with error "Too Many Open files". Then I increase the limitation from 1024 to 65530 for Tomcat. But the open files handlers keep increasing.

       

      The lsof return many ESTABLISHED sessions which seems hang up there.

      $ lsof -p `ps aux |grep 'Dcatalina.base=/opt/cmtools/tomcat' | grep -v grep | awk '{print $2}'` | grep 'bitbucket.org' | grep ESTABLISHED | wc -l
2221 

$ lsof -p `ps aux |grep 'Dcatalina.base=/opt/cmtools/tomcat' | grep -v grep | awk '{print $2}'` | grep 'bitbucket.org' | grep ESTABLISHED | tail

      In the tomcat log, I could see something about the bitbucket.org.

      I have check related two Jenkins plugins https://plugins.jenkins.io/bitbucket-build-status-notifier/ and https://plugins.jenkins.io/bitbucket-pullrequest-builder/ but don't find out any clue.

      I don't understand these log and ESTABLISHED sessions.

      The open file number keep increasing and I need to kill tomcat period then restart it.

      Appreciate for any help on this!

      Thanks,

      Darren
