      SSH Pipeline Steps plugin 2.0.0

      Memory is accumulating over time, eventually making some jobs fail with error
      java.lang.OutOfMemoryError: Java heap space

      I suspect it is connected to SSH pipeline steps plugin.
      Each jobs use this plugin several times and sometimes receives back very long logs.

      I attach a graphic of the memory accumulating over the months, while the number and quality of builds remained stable and a heap dump.

      I am not an expert of Java so plese guide me if you need something else.

       

      Thanks

          [JENKINS-64374] suspect memory leak

          Kevin USLU added a comment -

          I experience the exact same thing.

          I call SSH steps couple hundred times per pipeline execution and experienced recurrent agent crashes because of java.lang.OutOfMemoryError: Java heap space caused by memory leak seemingly caused by SSHStep Logger.

          The only way I could bypass it was by completely isolating these steps on a dedicated node that I kill when idle (3-5 minutes) and restart when needed to "clear" the memory.

          Would appreciate a proper fix.
