M204.1683  VMCF message limit exceeded

Model 204 has attempted to transmit data to a VMCF user (IODEV 39, 41, or 43), but z/VM cannot accept any more messages from Model 204. Before z/VM can accept any more messages, it must transmit some of the waiting messages. Model 204 waits one second and attempts to retransmit the data.

System manager response: This may be an indication that z/VM is overloaded, preventing the delivery of VMCF messages. If this is the case, take steps to reduce the load on the machine. If this error occurs repeatedly, and the load cannot be reduced, you may wish to apply IBM APAR II01071, which will increase the number of VMCF messages which can be waiting.

Operator response: Contact the Model 204 system manager.
