Hello, all!
I‘m not sure that the below problem is kernel related, however, I think,
this mailing list is the best place to start. I've got 2x1.8 Xeon on
Intel SE7500CW2 motherboard with Intel SCSI RAID (GDT driver). The
system powered by Red Hat Linux 7.3 with custom kernel version 2.4.27.
Occasionally, the system just hangs, without giving any error messages
to syslog or any panic-like messages to the screen. No response to ping.
Usually it happens on weekends in early hours, but not at particular
time and day, when users’ activity is minimal. Couple of times the last
few messages before, the hang had strange timestamps. It seems like the
system time entered a TIME LOOP within a period of 1 second.
Nov 6 05:37:31 service dhcpd: Message...
Nov 6 05:37:32 service named: Message...
Nov 6 05:37:31 service named: Message...
Almost all the time last messages came from different services, except
three times, when mgetty was the last. I'd updated mgetty, pppd, kernel
(from 2.4.20), BIOS, dhcpd etc., however, the problem remains.
Can anyone tell me, how I can detect, what application or hardware cause
such a problem.
Any ideas would be appreciated.
Thank you in advance
These are services being run on the server:
gpm
named
iptables
crond
ldap
smb
xinetd (swat amanda)
autofs
nfs
qmail
sqwebmail
dhcpd
ups
sshd
firebird
ntpd
httpd
arpwatch
drwebd
mgetty
pppd
postgresql
I have a similar problem at the moment, i have setup my box with gentoo
and now i get hardlocks from time to time (time < 1.5 days), happens
with and without x, kernel 2.4.27 untainted, with apic on and off, acpi
on and off, apm on and off...
@zergio: Can you tell me if it only happened with 2.4.27?
The system is really stuck when it crashes. My wireless keyboard has a
led to indicate traffic, an when system hangs, not even the led would
blink, it just stays in either on or off state (its normaly off). No
disk activity, mouse is locked, display remains unchanged (x.org nv or
plain (non-fbdev) console). Havent tried so far to reach the box over
network, but is suspect it will not work.
@developers:
Maybe thats a hint, could it be that a broken keyboard induces such
behaviour?
Im going to change kernel to 2.4.24 (had uptimes > 14 days with it) and
see if it helps.
As far as i can see, nothing was written to the logs, no messages, it
just peacefully dies...

No, it had happened with 2.4.20 kernel.

In my case it has happened with and without keyboard and with keyboard
connected to D-Link KVM Switch

There is no strict period of time. Some time server up for couple of
month. Recently the issue occured twice within 7 days.
It've happened 7 time during last half a year or so.

Go into the bios and disable USB keyboard support and USB storage/boot
off USB devices (however they phrase this in your BIOS). That *may*
help. It does for some similar reports.
