A high number of out-of-sequence buffers indicates high CPU utilization of the remote z/OS Communications Server address space. This is probably due to network congestion or constrained CPU in the remote z/OS Communications Server address space. To solve, validate the router configuration parameters, confirm that CPU utilization is high for the remote system z/OS Communications Server address space, and redistribute the z/OS Communications Server workload on the HPR RTP connected remote system.
