Here's a stacktrace. There's a bunch of stuff about locking and waiting in here on just about every thread; this looks like some kind of deadlock issue. I'll leave it to you guys to figure out what's up.
I found a post about a previous issue regarding deadlock:

This will almost certainly go away when we switch to our new IMAP/POP/LMTP framework, as it does network writes from a different thread pool. For now, we'll see what we can do to figure out a temporary workaround.
Thanks very much for the full thread dump! |
It doesn't seem the issues are related, however. Tomcat as a whole is going down here.
