Hi JC,

 

 

As a matter I'd suggest upgrading to 9.4.7 with the latest hotfix. There is a known issue in 9.4.3 and lower where this functionality may fail. The issue is described in SOL8160:

 

 

SOL8160: The BIG-IP LTM does not choose another pool member when the Action on Service Down setting is set to Reselect and the target pool member becomes unavailable

 

https://support.f5.com/kb/en-us/solutions/public/8000/100/sol8160.html

 

 

If after upgrading, the reselect on service down still doesn't work to reselect a new pool member for all existing TCP connections, I'd suggest capturing tcpdumps and ltm log files and opening a case with F5 Support.
