Can you run strace on the process, or use lsof to see if it's touching one of 
the dead mount points?

Subject: [ADSM-L] dsmc won't start/hangs

An odd situation popped up on a Linux client (7.1.3.1).

This client had been backing up just fine and suddenly it stopped.  Nothing
in dsmerror.log.

What is strange is you cant get into dsmc.  It simply hangs so hard you
have to kill -9 it.

The TSM server is still fully ping-able.  Tried renaming dsm.sys/dsm.opt so
it could not find it and properly reports this but as soon as they are
available/found, it hang?

The only clue/oddity we see is an NFS mount that is also
non-responsive/non-pingable and we are talking to the server owner about
rebooting the box.    Can this be causing the dsmc process to hang?

Any thoughts on how to diagnose this?
