Hi,
I was just digging through the FAQ looking for this and could not find it, so here we go... we have two sensors on our network, one listening on a one-way only interface and the other between our lan router and firewall. I've just now started looking at the Data (wasn't my job before) that has been collected for some time and noticed that some of the payloads are quite corrupted. Since the data captured is fairly useless, I'm going to be upgrading snort and moving the corrupted data to it's own little directory for "special" databases, replacing it w/ a fresh db; however, I'm asking this question now in the hopes that I don't run into the same situation again.

If anyone has anyideas, I'd love to hear them.
Cheers,
nick
