3.1 branch.
Now I'm browsing around the
com.caucho.server.port.TcpConnection._request which is never
explicitly release, but I realize it's getting a bit too late on
this side of the Atlantic ocean so I better continue tomorrow unless
you find the source of the problem until then.
That field is never released. The TcpConnection, Request and Response
triple are reused together.

I noticed this bug was marked as resolved, so I tried reloading our
webapp running on Resin compiled from SVN. Same problem.
Familiarizing myself a bit further with YourKit and comparing with
the sources, I believe both
com.caucho.jca.UserTransactionProxy._threadTransaction and
com.caucho.transaction.TransactionManagerImpl._threadTransaction
should be cleared properly.
Although I have not yet found the path to the HttpRequest. I could
send you my YourKit snapshot if that helps in tracking this down.

Although embarrassed to admit it, we have had long standing

with PermGen memory leaks. We have gotten used to restarting the

every time we redeploy, to avoid OutOfMemoryError. Since we would

to make use of - or at least evaluate - some of the new Resin
features
like WAR versioning, I thought I’d give fixing this another shot.
I've added this as http://bugs.caucho.com/view.php?id=3031
That ThreadLocal needs to be cleared in a finally block when the
request completes. I'll need to check on that.
