MSCNSWWA64 64 Bit Snapshot Worker


ECC Constrained Plan With ASCP Engine/UI RUP#32 <Patch 7495367>:

Users reported the same error condition in previous <Bug 8903352> - MEMORY BASED SNAPSHOT 64 BIT AIX FAIL APP-MRP-22086 APP-MRP-22075 APP-FND-00416 - The fix for that issue was the following:

LDR_CNTRL was set to 1G. So all the programs which over 1G will fail if exceed 1 G memory. unset the parameter and restart appl manager solves the problem.

The problem stayed away until Monday 15-FEB-2010. Now the problem has returned, BUT it only occurs every Monday on the ASCP plan run. All other days of the week the plan is successful. Please note they also have a 64 bit executable from <Bug 8617032> - SNAPSHOT FAILS WITH APP-MRP-22064 IN MRSNSS_SNP_SAFETY_STOCK, 6

Currently on Monday's, when it fails, the debug log file reports the following:

MSCNSWWA64 module: Memory Based Snapshot Worker 64 bit AIX

It was noticed calendars coming due to be extended, then extended them 5 years but it didn't help. Also the fact that it errors on Mondays every week and that's it is very peculiar.

The issue can be reproduced at will with the following steps:
1. Run ECC Constrained ASCP plan
2. On Monday it always fails
3. All other days it succeeds
