RE: TOMCAT OUT OF MEMORY

["Shapira, Yoav" <Yo...@mpi.com>]

Hi,
Can you take the suspected code out of a JSP and put it into a simple
Java command-line tester?  Then you could easily attach to a profiler,
see where that memory is going.   Plus this approach would allow you to
rule out bugs in the servlet container.

If such an approach is not feasible, you could still try attaching a
profiler to your server and seeing where the memory is going.  Profilers
like OptimizeIt will do this for you.

And finally, another type of idea: could it be that this is proper
behavior?  By that I mean, could it be that your application
legitimately needs more than 64MB of memory?
