Hi all,

I recently migrate from OAS to Weblogic 10.3.6, but now I'm having problems with CLOSE_WAIT connections and "can't identify protocol", I have modified the keepalive over IPV4, but I can see the CLOSE_WAIT connections are over IPV6

The application run in cluster and them are behind a balancer

The servers are inteops01 and inteops02

The balancer 30.176.213.5 and 30.176.213.6

I'll appreciate any suggestion in order to solve this issue.

Thanks in advance.

Kind Regards,
