Howdy,

>First off, we're running Apache 1.3.27 and Tomcat 4.1.17 with
j2sdk1.4.1_01

4.1.17 really?  Not 4.1.12/18/24/27 (the stable releases)?  If possible,
move to 4.1.27.

That is unlikely, but possible.  You'll need a bit more than an
impression to debug GC-related issues, though ;)  What specifically do
you think is happening, and why do you think it's happening?

One simple thing to do is remove -server and -Xms (keep -Xmx).  That
will make the JVM use its default and usually very stable GC algorithms.

That's also possible.  It's the first thing M$ tech support would tell
you: "you're running an unsupported driver/platform combination, update,
retry, and call us back if you have a problem."  Ticket closed as far as
they're concerned.  Can you get a later driver?
