Scheduler is terminated in the middle of backup

Hi there,

One of my AIX 4.1.5 client running ADSM client version of 2.1.0.6 is
experiencing very unusual problem.  ADSM server schedular contacts this
client at 21:25:00 and starts the backup and in the middle of performing
the backup, I get the following message in the nohup.out and the
dsmsched.log files:

06/02/97   21:37:49 ANS4102I ***** Processed    94,000 files *****
06/02/97   21:37:53 ANS4102I ***** Processed    94,500 files *****

06/02/97   21:38:13 ANS4483I Schedule log pruning started.
06/02/97   21:38:13 Schedule Log Prune: 399 lines processed.  0 lines
pruned.
06/02/97   21:38:13 ANS4484I Schedule log pruning finished successfully.
06/02/97   21:38:13 Scheduler has been stopped.

After which the nohup schedular process is terminated on the client and the
 event log on ADSM server gives the status
of failed.

The ADSM server is running on AIX 3.2.5 machine and the server level is at
2.1.0.12.

Does anyone has experienced error of this nature.  Any help or suggestion
will be greatly appreciated.

Thanks,
Naveed.
