garbage collection in asp.net

[Guest]

I've done some searches on the gc in asp.net and not 100% sure how it works. I just implemented a new asp.net system that accesses only sql2000. The primary architecture is the .net data access class (the one provided on microsoft's site), a data access layer that returns strongly typed datasets and the aspx pages that interact with the data access layer. If I keep an eye on the memory being utilitized by the worker processes (via taskmgr) I see it start at around 30K and will grow to around 140k. Will this memory continue to grow until the garbage collector deems that the heap is full ? Is there something wrong with my code ( a memory leak of some problem ) ? If I stress test the site 5 concurrent users running for over 2 hours pounding all the pages the memory only went up about 6k over the 2 hour period. In Java I've used the heap analysis tool (HAT) to see the behavior of the gc. Is there something similar in .net ?

Task Manager is not an exact way of monitering memory usage, if you watch it
for other programs under NT/2K/XP, you will see that much more memory is
allocated than is actually being used. You may want to consider using
performance counters and the app test center.

the heap is full ?

Yes, see the .NET docs on garbage collection for a complete explaination on
how the GC grows, collects, and populates generations.

Not likely. But no one could say for sure with out seeing the code.

Not that I know of. I did a search on google and MSDN, but found nothing
(althought, it was a short search).

what is the best performance monitor for me to add to check for the memory being used by my asp.net app
