Symptoms

After upgrading to DP 10.10/10.20, ALL AIX 7.1 clients backup were timed out and failed

Error message:

[61:1002]         The VBDA named "xxx [/var]" on host server1
            reached its inactivity timeout of 900 seconds.
            The agent on host will be shutdown.

With debugging enable, backup can complete successfully,

Diagnosis

Problem was due to the Inter-process communication was timed out.

One possible reason for backups failing for non-debugging and working fine for debugging is that while debugging it takes time to write and meanwhile communication between processes happen properly.

Solution

Issue is expected to fix on DP 10.70

At the moment, apply the hotfix DP1020_b115_OCTIM19Q761761_HF1_ux
