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.
