Phil Fenstermacher commented on DS-605:
---------------------------------------
I was having the same issue and found that a different startup script for
Tomcat fixed the problem. The script that would cause the behavior used the
arguments Xss and Xmn, however after they were removed things started behaving
correctly.
The presence of the arguments I'm sure is not what caused Tomcat to crash but
rather improper values set within those arguments. If I find better values to
use I'll be sure to post them.
