A CANCEL PROCESS command has been entered for the specified process, but the process specified is an automatic process, such as migration or reclamation, that cannot be canceled.
The server ignores the command.
If the process is a REPLICATE NODE process and is on the target server, it cannot be canceled if the process is in progress and the source server is available. The target server monitors communications with the source server. If 5 minutes have expired since the last communications, the target server assumes that the source server is no longer available, and the process is canceled. To view the length of time during which the process has been idle, issue the QUERY PROCESS command and specify the process ID for the replication process.
