HP DP 9 Internal error

Hi all,

We use HP DP 9.07 (RedHat 6.8).  The last week scheduled copy job failed wit error

[Critical] From: CSM@srv0050 "copy_job"  Time: 04/03/2017 08:00:02 AM
Internal error: DbaXXXX functions.

If I run the job directly, it completes without error.

I checked internal dB - it's OK.

Do you have any idea what is wrong?

Thanks a lot
