Hi Snort Users, I'm in need of some help... I am using FreeBSD 5.5 [Generic Kernel]. I installed Snort via ports. When I run snort with the following command line: "snort -i sis0 -v -c snort.conf -l ./logs" Snort trys to startup... what really happens... snort begins to consume RAM, once RAM has been fully consumed it consumes SWAP. Once SWAP is full, Snort will die and pfault - or so says top. I have included a snippet of output from top and snort. A nicely printed version is available at http://tinyurl.com/yxdekg Any help would be greatly appreciated!
