3413306 - Tomcat service abruptly stops

• Lately, it has been noticed that in certain environments, Tomcat server seems crashes every few days like 1-2 weeks.
• In these cases, Tomcat service shows as stopped in the CCM
• When Tomcat crashes this way, the users can be getting "Bad Gateway" message. 
• After restarting the tomcat, it runs for a few days and again crashes
• In all these cases, a tomcat dump is generated after the crash (eg: hs_err_pid1234.txt), with the following details:

• In most cases, Tomcat memory arguments are configured optimally. Parameters like maxmetasize 1+ GB and max heap have already been increased from 4 to 8 or 16g.
• There are no out of memory or heap space or stack overflow errors, nor anything indicative of load like running out of threads.
