CECC0326W (0x01020146) CECC0326W A stop replication timeout occurred. Replication shutdown processing for subscription subscription-name did not complete within the SHUTDOWNTIMEOUT value. Replication shutdown processing was forced for the subscription.

Explanation
The source server failed to complete its stop processing with the target server during the shutdown timeout period and declared a stop failure.
This can occur if the target does not provide expected response messages during the shutdown sequence.

User response
No action may be necessary if this message is infrequent.  This could indicate an intermittent connectivity problem during shutdown processing.

If this is a repeated message then more review of the target server may be necessary to understand why shutdown processing did not complete in a timely manner.

If the connection is known to be slow it may be necessary to increase the SHUTDOWNTIMEOUT value to avoid this message.
This provides more time for the shutdown processing to complete before shutdown processing is forced by the source server.
