This morning, one of our machines Oopsed while running dsmc (Tivoli
storage manager Backup-Archive client 3.7.2.0), dsmc itself caught
SIGSEGV:
08/10/2001 03:15:54 B/A Performance thread, fatal error, signal 11
This is somewhat peculiar since it should not be possible for a
user-space process to shoot a kernel process, and it's even more
peculiar because it breaks our daily backup.
Assistance is sought.

I tried stracing that beast (strace V4.2), but I failed, I only trace the
"Performance" thread which displays the dsmc progress. Is there any way
to trace one of the remaining two threads so I can figure which file or
directory the dsmc dies on?
