Hi Yury!
Before even starting to investigate, I would urge you to upgrade to a proper
server level. You are running a 1,5 year old patch release!
Kindest regards,

Hi all,
I have very unpleasant situation with my DSM server. It hangs 1 or 2 times a
week during the night backup. Every single client (I have 500 nodes) hangs
too. So After rebooting the server all client nodes have to be restarted.

We fixed all suspicious hardware problems, installed latest AIX4.3.3 patches
and DSM server patch, all installations did not help. I ran auditdb during
this weekends. It found a few discrepancies and fixed them. But last night
server hangs again.

There is no any suspicious messages or errors in the actlog. On some clients
in dsmerror file I see the following error:
10/27/03   22:26:48 ANS1005E TCP/IP read error on socket = 7, errno = 73,
reason : 'A connection with a remote socket was reset by that socket.'.

But most nodes don't have even that.

My environment is as follows:
AIX 4.3.3
DSM Server 5.1.0.3
Nodes mixture of versions from 4.2 to 5.2 versions.

Have you ever had or heard of such a problem and what would you recommend to
do next?

With respect,
Yuriy Us.
