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?
