Issue/Introduction

CA Datacom Multi User Facility (MUF) region is correctly shut down and the DBMUFPR step returns RC 0 but a SNAP dump (ID=20) is generated on the MUF joblog while the following messages can be found on the JESMSGLG:
DB01004E - PXX AREA I/O ERROR  
DB01001W - PXX AREA FULL       
DB00202I - MULTI-USER DISABLED 

Cause

The errors are returned because the PXX dataset is shared with another MUF region (a member of the same MUFPLEX, a shadow MUF or a completely different one) 

Environment

CA Datacom/DB or CA Datacom/AD 14.0 and above

Resolution

Each region must have its own PXX and this dataset cannot be shared with any other Datacom MUF region.
This requirement is clearly stated on KB000025223 for Primary/Shadow configuration.
