I've had this server up for quit awhile and every once and awhile it just
hangs. This happens once every couple months, sometime once a month at
various times of the day or night. The server is up and running. There
no response and no one can attach or login. The console is
unresponsive. I have no choice but to power off the server. When it
comes back up there is no indication as to what happened. The abend log
reporded nothing. Has anyone else had this problem? Any suggestion as
to how to nail down what is going on?
