Symptoms

Constrained planning in Pre-Production:

Have been running a successful ECC constrained plan up until recently with no problems then it started erroring in MSONWL64 module: Memory Based Planner 64-bit Linux with debug enabled with the following error:

Negative Buffer Problem: ITEM/ORG=3176/113; Qty=52906

Things tried:
1. They did remove the item (item name = 011001639, item_id = 3176) that was shown as the last item in the log file and the plan completed successfully for a couple of days. They put the item back in the plan and it runs successfully from time to time, but the error still pops back up intermittently


STEPS
-----------------------
The issue can be reproduced at will with the following steps:
1. Run ECC constrained plan
2. Remove offending item noted at bottom of the log from planning
3. Plan is successful
4. Put the item back in the plan - plan fails intermittently
