Jun 13 18:35:23 cache squid[17295]: Squid Parent: child process 30440 = exited with status 1 Jun 13 18:35:26 cache squid[17295]: Squid Parent: child process 30518 = started Jun 13 18:35:26 cache (squid): ipcache_init: DNS name lookup tests = failed. Jun 13 18:35:26 cache /kernel: pid 30518 (squid), uid 65534: exited on = signal 6 Jun 13 18:35:26 cache squid[17295]: Squid Parent: child process 30518 = exited due to signal 6 Jun 13 18:35:29 cache /kernel: xl0: watchdog timeout Jun 13 18:35:29 cache squid[17295]: Squid Parent: child process 30520 = started Jun 13 20:58:33 cache (squid): xcalloc: Unable to allocate 1 blocks of = 4096 bytes! Jun 13 20:58:33 cache squid[17295]: Squid Parent: child process 30520 = exited with status 1 Jun 13 20:58:36 cache squid[17295]: Squid Parent: child process 30633 = started This is a compaq proliant server with 4x500mhz Xeons, and 10x9GB SCSI = disks and 1.5GB RAM, running only squid server. The traffic which pass in and out is between 5-7mbits/s , I am using a 3com nic, because the compaq dual etherexpress pro hangs = permanently before! I have tuned the following in the kernel: options MSGMNB=3D16384 # max # of bytes in a queue options MSGMNI=3D512 # number of message queue identifiers options MSGSEG=3D8196 # number of message segments options MSGSSZ=3D128 # size of a message segment options MSGTQL=3D512 # max messages in system options NMBCLUSTERS=3D32768 also, have set the following in /etc/sysctl.conf : kern.ipc.somaxconn=3D1024 net.inet.tcp.delayed_ack=3D0 net.inet.ip.portrange.last=3D30000 The squid is running without diskd and is in transparent mode. I will appreciate any advices how to fix or tune more this squid-cache = server.
