CirrostratusHi Rick,
TMM would send a TCP reset as if the iRule wasn't there and the default pool was down. If you want to check the status of the pool before assigning it, you can use active_members. Or you could use the LB_FAILED event to handle this after a load balancing failure occurs.

You could also replace the if/elseif/else chain with a switch statement:
