I had posted this on freebsd-questions but till now have not received any kind of feedback which is fine. I need some help and suggestions from this mailing list if permissible. I am sorry if I am posting this to the wrong mailing list. I have squid proxy server running on a FreeBSD-6.1 (amd) box. I have been facing this problem for sometime now. It's related to mbufs. For some reasons, my mbufs usage is extremely high. This high mbufs usage causes slow responses from Squid and in rare occasions, it even causes my server to reboot or locks out SSH sessions. This FreeBSD-6.1 squid box serves about 3000-4000 users. Server specs are: Dell 430 Intel(R) Pentium(R) D CPU 3.00GHz-Dual CPU real memory = 2145959936 (2046 MB) bge0:
