Runaway Connection Counts on Virtual Server

Update on the situation-

 

I scheduled a maintenance outage to reboot the LTM. Got involved in another issue which was that the standby was not properly sync'ed. Tried failing over last night, but had to fail back before I could reboot the primary. The good news is that I fixed the config sync problem, so I hope to be able to schedule a new maintenance period, and I feel more encouraged that failover will work, and I'll be able to reboot the primary.

 

The connections did come down during the maintenance last night, but they quickly climbed back up over 40K, which still seems quite high. It May just be the increase in traffic - these are mostly mobile devices which are uploading data, so the sessions are quite brief (1-3sec). It may just be taking them longer to time out of the connection table or something.

 

Will try to post another update after I get this rebooted.

 

Cheers!
