I'd suggest upgrading to a more recent, supported version (at least to 9.3.1, or 9.4.7 or 10.0.2 when it's released).

 

 

What protocol is the virtual server (TCP/UDP)? That log message looks more like a TMM restart. There have been some issues with using the LB_FAILED event in the past. Here is one example:

 

 

 

LB::detach and LB::reselect in LB_FAILED call (CR97076)

 

In previous releases, having an iRule that performed an LB::detach or command LB::reselect in the LB_FAILED event might have caused the Traffic Management Microkernel (TMM) to restart. This version of the software first checks the connection, and if the system has already detached the connection, the process correctly does not try again to detach or reselect the server-side connection.

 

 

 

 

You might try opening a case with F5 Support on this so they can review your full VIP and iRule configuration. But I would be prepared to upgrade regardless.
