  • Hi KJ,

     

     

    Have you by chance set priority groups and have that enabled? Just so I know, if you go to the pool statistics you see 0 under the total connections column for the node in question?

  • Hi,

     

     

    Priority group is disabled.I check and both pool members showing "0" as connection Limit. pirority Group "0" for both member.

     

     

    VIP is TCP port, not sure if that helps you?

     

     

  • I also run 10.2.0. Let's start by providing some configuration info. Can you post the output of these commands?

     

    tmsh list ltm virtual

     

    tmsh list ltm pool

     

     

    If all your connections are coming from the same source address, then the persistence profile you applied to the VIP could explain why all connections are being sent to the same node. The explanation may be obvious from this info, but it may not.
  • did you tried to do a tcpdump and check how often the other server is responding.....
