[Snort-users] frag3 alerts

I am seeing a lot of frag3 Fragmentation overlap alerts with my DNS
server as the destination and a source address that reverses to a root
server. When examining the packets, the traffic seems to be valid DNS
traffic, although it has nothing to do with any domains that I host. Is
this some sort of attack, or is it valid traffic that is throwing false
positives? If it is a false positive, is there any way I can fine-tune
the frag3 preprocessor to avoid these?
