Thanks a lot Daniel for the prompt response,
Adding to what you said, we are also facing another issue (https://issues.jenkins-ci.org/browse/JENKINS-25870) which is related to proxy settings not working from plugin manager, anything related?
More Information: Recent config changes that we have done with our Jenkins master is we had added a couple of windows slaves to run selenium Tests on them and we already have a linux slave.
My apologies, if this issue is not related to this Tracker, we just want to corner the issue, It would be so grateful if you can help us in cornering the issue
Please let me know if you need further details,
Below is the part of Tomcat log on the day when earlier crash happened. Below errors are repetitively found in logs (for better understanding i had renamed the hostnames of windows and linux slaves as "windowsslave" & "Linuxslave" )
