Looking back at the JDBC API, I'm not sure you have any control over the
RSMD query, result, etc.

Well, thanks to Lamda probe and then to jmap, I have found my memory
leak. Here are the gory details in case anyone is interested. It's not
really a Tomcat issue, but rather the boundary between Tomcat and MySQL:

Hi,
the manager application can return values in XML. You just need to hit:-
http://localhost:8080/manager/status?XML=true
or wherever it's located. This makes it a bit easier to write shell
scripts based on Free Heap or Max Threads or whatever. I've got a perl
script which checks whatever value
To Ben & Mark,
Thanks for the replies. I've been trying various things based on your
suggestions. I find my best tool at the moment is "Lambda Probe" -

However with the latest set of upgrades rather "forced" upon me all at
once (instead of managed more properly), my application appears to have
a severe memory leak.
