Renaming a virtual server (essentially, moving one virtual server to a new location, which effectively renames it) might cause buffer overflow and potentially result in Failover.
Buffer overflow and potentially failover.
The database variable 'mcpd.mvenabled' must be set to 'true'. Also, when moving a virtual server, the new name must be longer than the original name.
Do not use the move command. Instead, issue a delete followed by a create command in a transaction.
Renaming a virtual server now works as expected, and does not results in buffer overflow or failover.
