R09110Z called from Orchestration/Service Request not processing all selected records

Hi,

We are submitting multiple runs of R09110Z (multiple versions with multiple data selections), initiated from Orchestrator Service requests. All running in single threaded queue.

Intermittently, we have one run that does not process all F0911z1 rows onto F0911 but still updates the EDSP to Y on F0911z1.

There is a slight pattern, in that the run that doesn't process all records is the first run of a specific version (multiple runs of same version are run with different Data selections)

We can see from logs that the fetch processing halts early but nothing obvious in logs to explain why.
