      Hi, I am running standalone instance of Jenkins version 1.514 in Linux. When many selenium tests are run, jenkins becomes very slow and even loading the browser takes a very long time. It has been like this for a long time. I got a heap dump at that time when jenkins was too slow. Can anyone findout what the issue is and let me know if I upgrade to 1.519 this issue will get resolved?
      Also, please let me know if you need any more details.

      Jenkins runs on 4 core processor with 8 GB RAM and 32 bit OS. Also CPU usage goes to 400% when multiple selenium tests are run and Jenkins is very slow.

      After sometime, Jenkins JVM crashed itself generating a log file. I have attached the generated log file also.

      Thanks, Aswini
