The funny things is that we have now a Pentium running FreeBSD 2.2.5 and squid with 128M RAM and a wide 2940 scsi controller and it never goes down! I even compiled a new kernel with all AHC_... options and still it is very stable. It was the same with 2.2.2. It does have a nice load as hundreds of users use this host as a proxy server plus it works with other squids remote as well. Both innd and squid is I/O intensive and uses lots of small files... Next week we try to use FreeBSD as a news server again but with DNEWS this time :) Also, I installed a new disk into the proxy server and during boot it says somethins like 'sending SDTR' when the controller negotiates with this new disk. What does that mean ? best Gabor Dolla DataNet Ltd, Budapest, Hungary
