Hi Matthew,

Yes, the root user ulimits is set to unlimited on all the AIX servers.

Good morning Pam,

We encountered errors backing up filesystems with large numbers of files until 
we set the root user ulimits to unlimited.  That fixed the problem but can have 
other consequences, obviously.  Do you know if your AIX admin tried changing 
the ulimits?

Regards,

Hello,

Recently one of our AIX administrators upgraded the TSM client to 7.1.4.4 on 
her servers. Many of them started receiving errors like

calloc() failed: Size 31496 File ../mem/mempool.cpp Line 1092

I looked this up and the indication is that the AIX server could not supply 
enough memory to TSM to complete the backup. We opened a ticket and were told 
to try memoryefficientbackup with diskcachemethod. This did not fix the issue.

In frustration the administrator reinstalled a TSM client version of 6.4.2.0 
and is no longer experiencing the memory problems.

Any thoughts?

Thank you,

Pam
