I doubt adjusting the stack size in any way will help. HTTP 500 is a web client to web server communication error and changing the stack size will not to much if this communication is failing in the first place.
Does the Tomcat server crash at the time you get the 500 errors? I'm doubting it must be but it would be a nice to know kind of a thing.. Is there any server or host referenced in the application that you built, that the web server may not have access to? Maybe there is a hard coded server name in the table fields on that application referencing a server that the web server cannot communicate with? Have you looked at the logs in the catalina.out file? These may tell you a thing or two. Also turn on your workflow logging for the mid-tier. This may tell you something too..

Tomcat did not crash. I have thread stack size = NuLL. Do I have to set a value for thread stack size ? This mysterious HTTP 500 status error still is not gone when I'm trying toaccess the custom built appllication through mid-tier while other Out of the box apps are opening fine.
