CirrusMySQL active connection never bleed off to other pool member
I am running galera MySQL behind F5 with performance Layer 4 type and i have setup 3 mysql node in pool member with Priority so only 1 mysql node will be used and other two will be standby.
...
The BIG-IP is sending a TCP Reset the moment the pool member with priority 100 goes offline/down.
(See article K15095 ).
The BIG-IP system sends RST or ICMP messages to reset active connections and removes them from the BIG-IP connection table.
Note: This selection is named "reset" instead of "reject" when using the TMOS Shell (tmsh).
And it seems your application is not trying to reconnect when it receives this reset.
