That is my problem -

In my regular logs I see nothing out of the ordinary. In fact this instance didn't seem to have a lot of traffic on it either. I am thinking that the javamonitor scheduled restarts are fubarring it up. I have turned off graceful scheduling figuring it had to kill the instances. I even set the session timeout to be like six minutes.

This is frustrating and is causing me a great deal of angst, embarrassment, and of course irate users.

Funny thing is this is only a read only app, though a very busy one 24 hours a day.

A session can only be checked out on one thread at a time. If you notice you are hanging waiting to check out a session. This means that a previous session did not check in properly when it was done. It's important to note that you don't have any session hanging doing anything else, so it's not like your session is stuck in an EOF deadlock. I can't remember if you're using project wonder or not, but if you're NOT, it is possible for exceptions to be thrown at certain places without it that can leave a session checked out and hung. I BELIEVE this can happen if a direct action throws an exception in certain places, and definitely if session awake or sleep throws an exception. Are there any exception stack traces in your logs that could have done this?

OK-

I think I got the correct thread dump from a frozen instance this morning:

What does it all mean?
