Hi, 

I have a server with Oracle application server running. A couple of
times we found that the process was hanged. The complain from the
application log was "running out of virutal memory".

The strange thing is our swaps were hardly used.

It seems like the application was only allocated certain amount of
virtual memory. Is there any kernel parameter that we can change or
this has to be done in the application level?
