Curious memory usage under Windows Server 2000

[Richard Toren <ri...@supportx.com>]

When I run Tomcat under Windws Server 2000 the Windows Task Manager 
shows an increasing memory usage over time (let's say 2 weeks) despite 
that the
manager jsp page (server/manager/html) always shows the same usage for 
Tomcat. Also the same Tomcat running under Linux has no memory creep.  I 
can't rule out a memory leak 100% (I'm using Berkeley bdxml which 
requires explicit destruction of instantiations of certain classes), but 
I'm fairly sure I've taken care of this.

Is the Window Task Manager reliable and if so are there applications I 
could use to track that usage better (eg  better time resolution)

Thanks

I'd use a profiler to see exactly what is going on. Personally, I use
YourKit but a Google search for Java Profiler should bring up a whole list.
