More Storage is required for OPS/MVS starting with Release 12.3. Storage required for a 30000 line message queue changed to 19200000 bytes in 12.3 from 11520000 bytes for prior releases.
 

Resolution

Increase the region size of the OPSOSF servers to 6Meg or change the region size for OPSMAIN to 0Meg.
