Mbuf issue

Dear All,

One of my FreeBSD 6.0 (AMD64) which is running squid shows high values
for mbufs.

I am new to FreeBSD, so I need your help and guidance.

Below is my netstat -m listing:

netstat -m

7701/3489/11190 mbufs in use (current/cache/total)
7614/1256/8870/64768 mbuf clusters in use (current/cache/total/max)
0/0/0 sfbufs in use (current/peak/max)
17153K/3384K/20537K bytes allocated to network (current/cache/total)
0 requests for sfbufs denied
0 requests for sfbufs delayed
0 requests for I/O initiated by sendfile
10120 calls to protocol drain routines

Sometimes, the mbufs value exceeds 64000 when the squid proxy is busy
and the server looses network connectivity.

Is it possible to control the mbufs in use. My other FreeBSD squid
proxy servers mbufs never exceed more than 32000.

Please shed some light on this issue. Also please provide me some links
to articles or tutorials on FreeBSD mbufs issues.
