Symptoms in Production

MPS relief worker is spawning many workers trying to process 500K lines this happens on a regular basis as we process many wip jobs/po lines

We are not currently using MPS plans or schedules.

Key profiles

MRP :Interface History Days = 2
MRP:Planning Manager Batch Size 5000
MRP:Planning Manager Max Workers 2

These were set earlier based on performance issue encountered in MPS relief workers.

Run standard MRP processes.
This bottleneck happens about 4 out of every 7 days.
Major DRP runs are over the weekend with smaller DRP runs during the week.

Performance team is concerned about these processes and many resources used to process these lines.
