Hi, I noticed, some months ago, frequent lockups on my RELENG_6 server with ECS PM800-M2, Celeron 2.6GHz (UP), 2GB ram, ATA HDDs and 3Com NIC(xl0), and then I gave up this old server.
Last month, I replaced this 'unstable' server to the new one with 7.2-RELEASE which worked very well until I setup it as 'a server'. The problem began just after it started 'the services'. My story is very similar to Pete's. http://lists.freebsd.org/pipermail/freebsd-stable/2009-January/047487.html I followed some instructions in the list thread. But unfortunately, the big problem still remains. 7.2-STABLE server locks up frequently. Help! :-( The server is NEC Express5800 S70/SD. o CPU: Intel(R) Celeron(R) CPU 440 @ 2.00GHz (2280.25-MHz K8-class CPU) o 6GB RAM o ACPI APIC Table: <NEC DT000020> o 80GB and 250GB SATA HDDs o http://www.heimat.gr.jp/~nakaji/localhost/dmesg.boot The kernel configuration is: include GENERIC ident HEIMAT options MSGBUF_SIZE=81920 makeoptions DEBUG=-g options KDB options DDB options BREAK_TO_DEBUGGER options QUOTA options DEVICE_POLLING options HZ=1000 options SW_WATCHDOG options DEBUG_VFS_LOCKS options INVARIANTS options INVARIANT_SUPPORT options WITNESS options WITNESS_SKIPSPIN options LOCK_PROFILING This server runs as web server, nfs server, dhcp server, ntp server, mail server with spam checks, ML server, usenet server and so on. From /etc/rc.conf*, there are some "_enable" lines as shown below. o ntpdate o ntpd o nfs_server o sshd o inetd o named o sendmail o rtadvd o watchdogd o dhcpd o snmpd o apache22 o samba o zope29 o zope210 o amavisd o amavisd_milter o cvsupd o ntop o compat6x o munin_node o spamd o spamass_milter o smartd o mailman o sshblock o innd o skkserv >From munin's graphs, the 'resets' value in netstat is increasing while on other 'desktops' it remains zero. Though I did not find if there is a threshold of 'resets', when it reaches to 0.8 - 1.2 the server gets "lockup". No ping response, no messages on cosole, no keyboard response, and, of cource, Ctrl-Alt-Esc does not function, when it locks up. I wonder why netstat's reset is increasing. I had learned a workaround from other Japanese guys, that is, enabling ichwd and running watchdogd can reboot the box when it locks up if the box has ICH. Exactly, after about 4 hours, the box rebooted while I was in bed last night. Watchdogd functions very well. Advice?
