Abnormal termination of an ISC TCP/IP session

Abnormal termination of an ISC TCP/IP session can occur as a result of transmission or protocol errors, or errors in data that make that data unacceptable to the receiving message processing program.

Because an ISC session involves two peer-level systems, error recovery processing and abnormal session termination processes can differ depending on which system initiated the connection.

Any work in progress at the time the of the abnormal termination is not completed before the session is terminated. When the connection is restarted, IMS and the partner subsystem must resynchronize the connection before any pending work can be finished.
