The preprocessors are "out of band" with the rules engine, the only interact through manipulation of the packet struct and data. The "fragmentation" we're talking about with this issue is RPC record fragmentation, not IP fragmentation, this is at the application layer, not the network layer.

In regards to the RCP overflow, is it possible to specify a "fragbits" option that does not specify a value of "0" ?
or will the preprocessor override any values in the rules files?
