Steve, You need to increase your MAXUSERS setting by doing a FILESERV REGENERATE for the file pool. Although it's buried, the 51010 reason code is mentioned in Chapter 5 of
the CMS File Pool Planning, Administration, and Operation manual: What Happens When the Limit is Reached: Logical catalog space is reserved during file pool generation. FILESERV GENERATE processing uses the MAXUSERS value to estimate and set the maximum logical catalog space. Whe n the server runs out of logical space, it displays a warning message on it s console and continues processing. Depending on their use of the file pool, users may receive error messages (DMS1146E) and error return codes (with reason cod es 51010 or 51020). When the logical catalog space is exhausted, you need to increase the MAXUSERS value for the file pool. Follow the instructions in Chapter 11, “Regenerating a Repository File Pool,” on page xxx. Thanks, Sue
