I can't understand what is missing to run Squid on a Freebsd 6.0 decently in a Dual PIII 750Mhz with 1gb RAM, 4 SCSI HDs with 18gb each. We have in the past a Freebsd 4.8 box running squid for months without big problems, but with Freebsd 6.0 we are being crazy. Squid runs well for 1 or 2 days and become very slow... I'm sending the configuration we are using here. Any idea or tip will be apreciated. loader.conf autoboot_delay="5" kern.ipc.maxsockets=32768 kern.ipc.nmbclusters=32768 kern.ipc.nmbufs=131072 kern.ipc.nsfbufs=6656 kern.ipc.shm_use_phys=1 kern.maxfiles=32768 kern.maxproc=8192 kern.maxswzone=33554432 kern.nbuf=16384 kern.ncallout=32768 kern.vm.kmem.size=268435456 kern.vm.pmap.shpgperproc=2048 net.inet.tcp.tcbhashsize=16384 sysctl.conf: kern.polling.enable=1 net.inet.ip.fastforwarding=0 net.inet.tcp.path_mtu_discovery=1 net.link.ether.inet.log_arp_wrong_iface=0 vm.v_free_min=131072 vm.v_free_target=262144 vm.f_free_reserved=32768 vm.v_free_severe=65536 vfs.vmiodirenable=1 kern.ipc.somaxconn=8192 kern.ipc.maxsockets=16424 kern.ipc.maxsockbuf=16777216 net.inet.tcp.sendspace=1048576 net.inet.tcp.recvspace=1048576 net.inet.udp.recvspace=65535 net.inet.udp.maxdgram=57344 net.local.stream.recvspace=65535 net.local.stream.sendspace=65535 interesting things from my kernel: options MSGMNB=16384 options MSGMNI=41 options MSGSEG=2049 options MSGSSZ=64 options MSGTQL=512 options SHMSEG=16 options SHMMNI=32 options SHMMAX=2097152 options SHMALL=4096 options MAXDSIZ="(1024*1024*1024)" options DFLDSIZ="(256*1024*1024)" options DEVICE_POLLING options HZ=1000 Squid: Squid Cache: Version 2.5.STABLE12 configure options: --prefix=/usr/local/squid --enable-snmp --enable-storeio=diskd,ufs --enable-err-language=Portuguese --enable-default-err-language=Portuguese --enable-delay-pools --enable-underscores --enable-removal-policies=lru,heap Thanks in advance Edinilson --------------------------------------------------------- ATINET-Professional Web Hosting Tel Voz: (0xx11) 4412-0876 http://www.atinet.com.br
