Serailization-Update not possible; event handler is locked

We generate serial numbers in OER pass them to Aii and the outside partner will request the numbers from Aii. Once they apply the numbers to our product, they will send an association PML file back. We are receiving the serial association file from the external partner through PI. THe file comes into Aii correctly (SSCC pallet and two GTIN (case and bottle), we can see the pallet linked to case linked to the bottle. When the file gets passed to OER we get error Update not possible; event handler is locked in SXMB_MONI and not all the numbers will be in OER.

This does not happen with every file, one will work but the next will get the Update not possible; event handler is locked error. The data is the same, the number ranges are the same. The number range being used was uploaded from Aii into OER and is blocked in OER, could this be causing the issue?

We have looked at OSS note 1968226 but we are on service pack SCEMSRV 900 and the note applies to lower version service packs. We have increased the size of the lock table but are still getting the error.

Any suggestions how to fix?
