iRule causing sync problems

We are having issues with the following iRule:

when HTTP_REQUEST {  
set http_request_time [clock clicks -milliseconds]
set request_log_line "\
HTTP::request_num],\
 [IP::remote_addr],\
 [HTTP::method],\

 [SSL::cipher bits] "

We have this iRule associated with a Virtual Server and when we do a configSync the following error is reported:

Configsync Mode: Push

Can anyone offer some insight as to why this may be happening?

Thanks in advance.
