In ltm log this logs occurs.

 

May 15 21:36:50 local/tmm1 warning tmm1[5207]: 01010213:4: L3 Address LB method deprecated; using 'Least Connections' for pool highway-ts_443

 

pool highway-ts_443 { lb method l3 addr action on svcdown reset monitor all gateway_icmp members { 218.145.47.109:https { monitor TCP_5_16 } 218.145.47.117:https { monitor TCP_5_16 } } }

    L3 Address load-balancing was introduced with the intention of being good for systems with trunks. Basically, it tries to choose a "compatible" (meaning "likely to cause trunks to be evenly loaded") pool member based on L3 connection information.

     

    To avoid seeing the warnings change the load balancing method to least connections,ratio or round robin which are not deprecated
