oh, there are many options (I think you have no rules with 
the tag keyword.)

  + disable strem4 which reassembles tcp packets. But this is not
    a good idea since you will be blind against fragmented attacks.

  + do not use the unified output plugin, this is the location 
    where the reassembled tcp packet is split into tagged once

  + edit the unified output plugin to log the full reassembled
    packet as it was with earlier versions of snort...

Best regards

Dirk
