Hi Lucern,

In fact Some person notify me that in some case / version (sometimes when we don't set a backend) we can have this kind of problem. I advise you for the moment to disable the following lines

serverside {
   log local0. "uid: $uid - pool member IP: [IP::remote_addr]:[TCP::remote_port]"
}

In 2 event:

when HTTP_RESPONSE

and

when HTTP_RESPONSE_RELEASE

I will fix the problem tomorrow and keep you in touch (and add caught function in order to avoir TCL error).

I think it was due to serverside command, because of server side connection does not exist... and I reassure you it's not normal behavior. When it will be corrected you will be able to use it without problem.

regards,
