iRule persistence issue (aka persistence isn't working)

I have the below iRule that seems to only ever direct traffic to a single node in a pool, despite the $vws_id variable being unique for each user session. Anything obvious I'm missing?   when CLIE...

Okay then, time to shoot from the hip a little.

 

  1. Do you have OneConnect enabled in the VIP? I'm not sure how it would affect this particular protocol though.

     

  2. In the TMSH persistence list, do you see that each persistence record is pointing to different pool members or the same member?

     

Again, just spitballing, but it could be that all of the clients are actually getting load balanced to a single server, or that maybe the TICKET value isn't getting read correctly with the persist uie command. Can you add a log statement in the iRule that shows a persist lookup (along with the client source address) and see what that gives you?
