If you see problems in the stacktrace, when the session gets checked out from the session store, make sure you NEVER EVER touch something from the session's default editing context inside your "performAction" method on a long response page. This will autolock your session's default editing context, it will not get unlocked, because you are outside of the rr loop and the next checkout for that session will fail.

This particular deadlock should be fixed as of a couple weeks ago after we talked, btw ... I think I rolled autolocking into long response, also. But generally speaking, if you're in another thread, I would lock manually to be safe.

Also, if you ever access an EODatabaseContext directly, you MUST lock that yourself. It will not autolock, and that will cause terrible problems.
