I have a problem with a 2.0.1-RELEASE (amd64)built on Mon Dec 12 18:16:13 EST 2011
16GB of RAM
2 Interfaces WAN bridged to LAN (transparent Firewall)
It all runs fine then it starts to drop connections and then the web GUI starts to slow down to the point you get Unavailable message. CPU sits around 10-15% so it isn't a CPU issue but I did notice that the MBUF was maxed out.
I am running snort and pfblocker.
25440/2724/28164 mbufs in use (current/cache/total)
24961/639/25600/25600 mbuf clusters in use (current/cache/total/max)

0/0/0 sfbufs in use (current/peak/max)
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
0 calls to protocol drain routines
I am wondering where I go from here.
Increase nmbclusters, it's covered here:
