APO Batch job is failing due to some DB error

Issue:

There are some batch jobs in APO process chains  which are designed to run parallel are failing quite often due to some DBA Error. However, it runs successfully after repeating failed job.

For example: Attaching both error and successful log

Note : There is no lock between CVCs or APO data, both Variants use different set of combinations and data gets lock on aggregated level.

            Also I have checked manually in system, it not locking the entries.

Since its a DB error i think the system is not even touching the combinations and failing before in DataBase itself. Can anyone suggest me on this issue ?

Thanks,
