I have seen seen symptoms that imply the same thing, although I didn't
realize it was that bad!
I have this verify apply which check an entire web hierarchy for
broken links, and after a while, it just dies. All my socket connect
attempts fail, and it hangs up my NT machine pretty badly.
I've also noticed that the NT version doesn't properly dispose of
Threads. My thread handle count goes up continuously until I kill
hotjava.
Hopefully this will be fixed in the upcoming chicago/NT release.
