Re: Transparent proxy

[Bolanle Akinpelu <akinpelu at skannet.com>]

Hi,

I had encountered the same problem before running squid on FreeBSD. It
means the buffer allocation in your FreeBSD kernel is in-adequate. I
increased the value of the buffer and recompiled the kernel and I was ok.

You can use sysctl kern.ipc.nmbclusters to check the current buffer
allocation. I tweaked mine from the default 1024k to 8192k. You could use
more or less. To change, I edited /usr/src/sys/kern/uipc_mbuf.c
looked for NMBCLUSTERS and changed the entry from 512 *(16 bla, bla) to
read # define NMBCLUSTERS 8192.

After the changes, recompile your kernel and should be ok.

Pls back-up the uipc_mbuf.c file before making any changes.
