Hi Gary,
I am sorry for the late reply.
I had lowered my net.inet.tcp.{recv,send}space to 16384/32768.
It seemed to help lower the mbufs usage at first but after about 2-3 days, the mbufs usage is almost the same.
I am looking into the sysctls forwarded by Alessandro.
I will continue to monitor net.inet.tcp.{recv,send}space values too.
Thanking all of you.
