CP READ canceled due to message buffering ‑ system access aborted

Reason

When you tried to access CA ACF2 for z/VM, it found a condition that required a reply to complete the access. CA ACF2 for z/VM is returning the command responses to a user buffer that indicates you executed the command through EXECIO or DIAG x’08’ with buffering. A CP READ to get the reply could hang this exec or program. CA ACF2 for z/VM cancels system access. A previous message describes the condition that caused the canceled CP READ.

Action

Take the action the previous messages indicated, then try again.
