I don't know about iRule error message.

We make simple irule for 2 byte udp payload based LB. when CLIENT_DATA { set index1 [UDP::payload 2] set div1 [expr (($index1)%2)] log local0. "index_6001: $index1" log local0. "div_6001: $div1"...

Wow!. It' works! Thanks a lot of your answer.

But we have another problem

I changed a little. But I got another error log.

That was "Address in use" error. But iRule is working well when occur error log.
