Mac fails to backup

Hi all!

We have defined a nightly schedule to do an incremental backup of some of
our server computers (some NT, some Macintosh); all of them backup without
problems, only one Macintosh is failing.

When I try to start the incremental backup manually, via the Mac GUI
client, the Mac crashes during the backup.

The client is ADSM 2.1.0.6, it communicates with the server (MVS) with
TCP/IP (Open Transport 1.1.2; yes - I remembered that there were some
problems with Open Transport TCP/IP, and I searched the ADSM-L archive, but
I found nothing about this version; TCP/IP is configured correctly, as this
system acts as a web server; and another Mac that is included in the same
schedule and that uses the same software backs up just fine).

HELP! Anybody out there that has similar problems? Anybody that has an idea
on how to solve the problem? (I've included the relevant informations from
the logs below; ask if You need more informations!)

TIA - Alfred Novacek


Here is the corresponding event entry from this night:

The activity log of the server shows following messages regarding this client:

The client's schedule log displays (I've shortened the sequences of entries
that show normal operations):
