[Snort-users] Snort ignoring stream4

After upgrading from 2.6.0 to Snort is using a much greater
amount of CPU and memory.  After looking at perfmonitor output, it
seems to be maxing out at ~ 8K sessions pretty much 24/7 despite the
following in snort.conf:

preprocessor stream4: disable_evasion_alerts, server_inspect_limit
300, memcap 209715200, max_sessions 2048

It seems to be ignoring max_sessions and memcap both.  Any body else
run across this issue?  It's causing the sensor to peak at around 20%
packet loss during high traffic periods.
