War file redeployment causes issues in Openshift

Issue

• Sometimes when I redeploy a war file in Openshift on Linux it process successfully and when I access the URL everything works fine but must of the time when I try to redeploy the same war file after performing some updates on my codes, it doesn't deploy successfully anymore. Even though I get successful message after the "git push" but when I access the URL nothing loads. I have restarted my Openshift platform several time and it still doesn't work. Sometimes when I rename EXACTLY the same war file it works fine and URL loads successfully but sometimes it doesn't.

• Below error is seen in the logs :
