spp_stream4 Stealth Activity detect

Hello All, I'm constantly getting alerts (40-100 per day) from the stream4 preprocessor for stealth activity. When I look at the packet trace, it looks benign (web traffic), except for the Ack/Push/Reset flags being set. My understanding of the Stealth alert is that there's no matching state info in the state tables that snort keeps. Is it possible that the state tables are 'flushing' too soon, or I just don't have enough memory for the type of traffic I'm monitoring? Am I way off? Thanks in Advance, John H. ------------------------------------------------------- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.
