The outstanding write to operator with reply (WTOR) messages have filled the buffer.
The system puts tasks issuing WTOR macros in a wait state until the operator either reduces the number of outstanding WTORs or increases the number of WTOR buffers.
The value of RMAX controls the number of digits in all reply IDs. For example, increasing RMAX to 100 (or higher) causes all WTORs to have 3-digit reply IDs. This might affect automation routines. Check with the system programmer before increasing RMAX higher than 99.
If the shortage recurs, increase the value for RLIM or RMAX in the CONSOLxx parmlib member.
