Hi Chris, My stream4 and frag2 configurations are by default in 1.8.7: preprocessor stream4: detect_scans, disable_evasion_alerts preprocessor frag2 There are about 10,000 hosts in my network, and the kind of traffic ... ummm ... I'm monitorizing an University, so HTTP, FTP, p2p I think. And, what did you mean with "I wouldn't be suprised if those times are when you are hitting a forced session prune." Thanks.

We can see traffic received in packets per second with blue line, Snort droped pps with green line and Snort total VM size in kilobytes. X axe represents time in hours (a little more than one week). First, why droped packets are so different in between days with similar traffic? (I get droped packets with a script that compares received packets from the interface with Snort processed packets, from kill -USR1). Second, why Snort vsize is like this?. I thought it bears relation to traffic received, but it doesn't.What are your stream4 and frag2 configurations? How many hosts are you seeing on your network? Any idea on the type of traffic? You might try running your statistics with a higher memcap. I wouldn't be suprised if those times are when you are hitting a forced session prune.
