A pool member or node monitor may unexpectedly transition from up to down and back to up even though the pool member or node has not failed.
BIG-IP system might send a premature FIN on the connection. This might result in unexpected monitor flapping even though the monitored object has not failed.
One or more of FTP, IMAP, POP3, or SMTP monitors are in use. This might also occur with monitor types other than those listed.
None.
BIG-IP system no longer sends a premature FIN on the connection, so unexpected monitor flapping no longer occurs, in this case.
