Oracle backup failures during TSM inventory expiration

[Givesgoodemail]

Has anyone run across a situation where attempts to backup Oracle databases and logs (via TDP-O) fail while the TSM server (running AIX 6.1) is doing its db2 inventory expiration?

I have seen this phenomenon since we upgraded the TSM server from 7.1.0.0 to 7.1.4.102, and I can find no documentation on the phenomenon.

Errors messages look like this:

03/04/16 14:40:06 ANR0406I Session 3214 started for node SERVER1_ORACLE (TDP Oracle AIX) (Tcp/Ip SERVER1 (57126)). (SESSION: 3214)

Since expiration doesn't use volumes, it's a coincidence that it happens during the same time.

Are there more error messages for that session?
