The JVM just ending with no message is odd.  Some things to consider:
- look at the system log, you might have developed a hardware problem that is 
causing the process to seg fault (or similar) and exit
- do you have scheduling on and something is preventing it from restarting?
- do you have some code that is calling exit() on the Runtime?
- Wonder has some code that will kill an instance if it runs out of memory (and 
maybe if requests take too long, I don't recall offhand what got left in), but 
I would expect that to log something
- override terminate() in Application and log out a stack trace
- did you change to a different JVM?  Maybe you got one with a defect?

I have an app that has been in service for a long time in various forms. 
Recently I deployed an updated version that has been in development in recent 
months. The update has been experiencing "silent" deaths every once in a while. 
There is nothing in the app log that indicates any exception that may be 
occurring when this happens. What I do see is loads of messages in the logs re: 
CookieParser: Found a null cookie value in....

However, this was occurring before. Sometimes I'll simply see a few logins that 
appear normal, a bunch of CookieParser errors, then the app log just ends. 
Maybe an exception is getting swallowed somewhere but I can't find anything 
like that.

Any suggestions?
