Description

Original: 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. Thanks, Aswini

I have attached the generated log file also. Thanks, Aswini
