Re: AIX client dumping core during backup

        Interesting,
        We too have over 70 AIX clients on our TSM server, but I have 1
client that coughs the same error about once a week:

03/11/01   16:00:11 B/A Txn Consumer thread, fatal error, signal 11

        The client is running AIX 4.3.3, and running TSM client version
4.1.2.0. The server in my case is also an AIX host running AIX 4.3.3 and TSM
server version 4.1.1.0. Our library is also a 3494 with 3590E drives. We
have tried uninstalling and reinstalling the client but it did not resolve
the problem.

        The odd thing is that during the day, many archive sessions are
pushed to TSM with no problem, but the scheduled incremental backup causes
this error once in a while. Stopping and starting the daemon on the client
fixes it for a few days, but it inevitably comes back. I have not opened a
case with Tivoli on this because I have other priorities, but I too find it
perplexing...
