What is the getfield entry do? And is that causing the issue. Does the messages in the logs means the irule is failing all the time.i guess you are using route domain. getfield is used to remove route domain part from IP::client_addr. 

[root@ve1023:Active] config  b rule initrule list
rule initrule {
   when RULE_INIT {
        log local0. "\[getfield 1.1.1.1 % 1\]: [getfield 1.1.1.1 % 1]"

        log local0. "\[getfield 1.1.1.1%123 % 2\]: [getfield 1.1.1.1%123 % 2]"
}
}
