What level of the server are you running?  The crash is fixed in the 3.7.3.0
level of the TSM server.

I am using v3.1.2.20 on AIX 4.3.2. I asked support if this had been resolved
in 3.7 and they said no, it is still an issue, but that was before 3.7.3 was
released. We will soon be going to v 4.1, so I will change my scripts back
at that time and see what happens. Thank you for your input.
