High connection rate (millions conns/sec)

Thanks to all who chipped in with a reply.

 

 

I've tracked the issue down to the active unit failing and the backup unit taking over (we have a HA setup). I can only assume that cacti goes a bit "crazy" when this sort of event happens hence why the connection rate is so high. Atleast the graphs pointed me to an issue.

 

 

I went searching the ltm logs and found that the F5 interfaces had gone down (maybe due to duplex mismatch).
