Looks like I accidentally replied to myself rather than the mailing list. Doh! I went to say that snort-1.7, with no optimization, ran for about 8 hours yesterday, then cored anyway. Perhaps I should rebuild libpcap while I'm at it, eh? Solaris 8 users: are you running gcc 2.95.3, and older version, or perhaps Sun's C compiler? I'm curious about this... Phil Wood wrote:

I'll try that...
Remember this is beta TEST mode, there are a number of areas in the code where ifdef DEBUG's have not been inserted.
Right - I was just hoping that if I didn't wander too far out into the woods, I'd be safe, or at least get a different perspective on the coredumps I've been having with 1.7.
I've also seen problems with defrag, but have not gotten any confirmation. It is my experience that certain fragment sequences in conjunction with some unknown force cause the creation of mutant packets, that is: IP: proto=icmp (20 byte header) DATA from somewhere in snort memory (not another incoming packet) Makes for some real weird ICMP type / code packets if you are looking for that sort of thing. Later,Upon startup, I get hundreds of "freeing AVL node" messages and then after about a minute or so snort complains that "max nodes reach, data is not inserted" after which it segfaults and dumps core.This is all stream3 stuff.Whee.
