Don't bother with jhat, try eclipse Memory Analysis Tool instead. It's much
more friendly and efficient to find leaks.

Hi,
I'm new to Tomcat management, and would appreciate help on the 'maxThreads'

Suppose I configure 'maxThreads=100', and 130
Some short answers :
- (for the moment) threads are always reused, even after an application is
stopped.
- tomcat 6.0.26 tries to clean the threadlocals which may provoke a leak, but

It is do-able if you are prepared to accept the associated constraints:

I also think that logging leaks may be more helpful than using part of
manager, because many don't deploy manager (they remove it).
it is logged when the application is stopped, on recent tomcat 6 and 7.
I think your approach to finding leaks by performing comparisons is
have a look at the bindOnInit parameter on the connector

My personal advice with the Oracle driver is to put it at the server level, not
at the webapp level.
For instance if you use the query timeouts, oracle JDBC spawns a Thread to
handle the timeouts, and there is no way to properly stop this thread so tomcat
will continue complaining about leaking

keep a watch on https://issues.apache.org/bugzilla/show_bug.cgi?id=51741 . When
it is implemented, it should give you this functionality.
