The number of write to operator (WTO) messages is 80% of the limit value specified in the MLIM parameter of a CONSOLxx parmlib member.
Processing continues. Consoles that are currently in HOLD mode and have messages waiting are taken out of HOLD mode. The system will no longer hold messages for other systems in the sysplex. If another system is experiencing a WTO buffer shortage, this system will resume sending messages to the constrained system. The system issues a D C,B command and a D EMCS,ST=B,L=Z command.
Before the next system initialization, increase the value of MLIM in the CONSOLxx parmlib member to increase the maximum number of buffers that WTO messages can use.
