Environment:jenkins 2.121.1
At some point in time, with the increase in the number of builds on Jenkins, we faced a "Too many open files" exception in Jenkins log.
Analysis of lsof command output (lsof-jenkins.zip
) showed that there are a lot of open files in some projects (Freestyle or Maven type)Â created at build completion on Jenkins master with name:
{$JENKINS_HOME}/jobs/test_project/builds/140/GetJUnitTestResults4300391778772244764.tmp
I found file with non zero size with the folowing content:
$ cat GetJUnitTestResults1715785790472604747.tmp

So I decided that hp-application-automation-tools-plugin leaves files opened after build finish.
The graph shows number of opened files by jenkins process. The red line is when plugin turned off
