Deploying WS on Tomcat

["Carlos S. Zamudio" <cs...@yahoo.com>]

Hi,. I have a general question about deploying Web Services on Tomcat 
(6). I'm trying to set up a sort of compute server on Tomcat where web 
services requests are called to execute an algorithm and return the 
results. I use AXIS2 for the WS communication protocol.
I'm running benchmarks on CPU and memory utilization on Tomcat and I am 
wondering what the mechanisms are for Tomcat to free up resources once 
it has completed the calculation  request.  What happens now is that I 
quickly run out of memory for a simple test case of a series of 
sequential requests.  Is there a persistence of the session until some 
future timeout event?

Thanks in advance for any suggestions.

Standard Java garbage collection rules apply.

Do you actually get an OutOfMemoryError?  What heap size are you
running?  Is your application failing to clean up after itself?  (That's
the most likely problem.)

Have you looked at the FAQ:
