SSL and mblb

I want to load balance using \n as the message delimiter from a persistent connection to F5. I wrote this iRule using a sample available in this site and added mblb profile. But it is not working. I have two nodes in the pool but only one gets the messages. Is there anything I am doing wrong in this?

when CLIENTSSL_HANDSHAKE { log local0. "handshake recvd from [IP::client_addr]" SSL::collect } when CLIENTSSL_DATA { while { [regexp -indices "(.*?\n)" [SSL::payload] transaction] } { log local0. "A complete transaction was found between [lindex $transaction 0] and [lindex $transaction 1]" SSL::release [expr [lindex $transaction 1] + 1] TCP::notify eom log local0. "Released and notified a message to be routed by the LTM" } SSL::collect }
