Service machine CMS terminal read entered

Reason

CMS called its terminal read routine that was intercepted by the CA ACF2 for z/VM service machine module. The service machine never issues a CMS terminal read. This message is followed by message 330I. CA ACF2 for z/VM issues a VMDUMP command and the service machine logs off.

Action

Review the service machine log and CP operator log for any messages that indicate a CMS error and take any appropriate action indicated by the error message. Otherwise, save the console logs and the dump and contact CA Support.
