Hello,

 

 

What is the persistence method you're using? Can you post the persistence profile settings by running 'b profile PERSIST_PROFILE_NAME list'?

 

 

Roughly how many connections are on each pool member? I assume the higher number of connections is due to one or more clients matching a persistence record. This may be a lot of AOL users connecting from the same pool of proxy servers or another group of clients making requests from behind the same proxy. If so, using cookie insert persistence and a OneConnect profile would help alleviate the clumping.

 

 

You may want to consider changing the load balancing method from round robin to least connections or another algorithm that takes into account the number of active connections to each pool member. For more info on the load balancing alogrithms, take a look at the pool settings in the LTM config guide for your version. Here is the 9.3 chapter (Specifying the load balancing method Click here).
