      Description

      When I am running a matrix job, after all the children pass the build successfully, the parent slave suddenly fails at the end of the build.

       

      This happens sometimes, and a reboot always helps to solve the problem, but after some time, it happens again, and we need to reboot the parent slave again.

       

      • it happens only on parent slave in matrix jobs.
      • Lately, we changed the JVM options Maximum Heap size to 7GB when connecting the parent as Jenkins slave, it didn't help either.

       

       

      This is the error it produces:
      FATAL: Remote call on parent_slave failed
