Hi - we are facing the same issue in our Production Environment (TMOS-BIG-IP 12.1.2 Build 2.0.276 Hotfix HF2; 2x BIG-IP 4000 in an Active / Standby Cluster Pair) with one of our Virtual Servers where we enabled the "Connection Limit / Connection Rate Limit" feature; similarly to what Joe Lupo posted, also in our Active / Standby Cluster Setup the "Connection Rate Limit exceeded" notification for the specific Virtual Server is reported only by one of the unit of the Cluster (the unit that we have currently set to Standby), even under low traffic volume.

 

The other unit (formerly set to "Standby" - now currently running as "Active") do not report any error notification message.

 

Did you manage to solve the issue ? Is there a way to clear the wrong notification message that is automatically presented on the standby unit of the cluster ? To me it sounds more and more like a Feature Bug. Is there already an entry in the F5's Bug Tracker DB ?

 

Thanks.
