this has something to do with your ulimit .. i am not sure how it's done on FreeBSD, as i am running my Squid server on SuSE Linux .. but, in Linux, there is a file called /usr/include/bits/types.h .. which has this field.. /* Number of descriptors that can fit in an `fd_set'. */ #define __FD_SETSIZE 1024 this is the default setting.. what u need to do is up this number to say 8192... after u save the file, u need to run the command ulimit -HSn 8192 in the shell the squid starts in... it would be better for u to put this command in a startup script, in a shell environment u reckon squid will start up, otherwise the shell won't pick up the new FDs and thus, won't pass them on to servers running in that shell, ie Squid... but, as i said, this is on Linux, i am not sure how this can be done on FreeBSD... good luck..
