Have you got RMF, and if so does that show TSM waiting on any resource?

Subject: TSM 4.1.0 on OS/390 2.9 hang
Hello All
Our TSM server is experiencing intermittant problems (on average every
second day) with these characteristics....
1. TSM is consuming a lot of CPU resources.
2. There is no TAPE I/O activity occuring when I know there are
migrations/reclamations running.
3. I'm unable to logon to TSM using dsmadmc. The login attempt hangs and
eventually times out.
4. There is no activity being recorded in the TSM activity log (ie syslog).
5. There is nothing unusual prior to the last entry in the activity log...no
errors.
Sometimes after and hour or so of TSM doing nothing productive, things come
right and everything continues on as normal. Leaving an hour or two's gap in
the activity log.
On other occasions the TSM server grinds to a halt..Zero CPU activity and
Zero tape I/O activity, resulting in us having tp recycle the TSM server.
We are running TSM with a region size of 1280MB.
I know we are back level in TSM server maintenance and are in the process of
migrating to TSM 5.1, but in the meantime has anyone on the list seen
something like this or can suggest what I can do to resolve this problem.
Thanks
