What does "no peer connection established TCP::collect" mean

I have an irule doing some checks on SMTP and I get a lot of:   CLIENT_DATA> - no peer connection established TCP::collect needs an established peer connection! (line 124) invoked from within ...

I think I figured this one out myself. This VS has 2 iRules attached, the other one being MSM, a f5 product that does RBL checking and when it decides the user is from an untrusted IP it drops it. As both of them start TCP::collect and in some cases MSM drops the connection and this other iRule finds out there is no more session present and logs the above error. Hope this will be useful to somebody as there is very little reference to the above error around..
