[cobalt-users] Spontaneous reboot ?

[Fabrice Prémel <fabrice@xxxxxxxxxx>]

Hi,

I was logged on our Raq3, via telnet. All of a sudden, I saw the 
following message :
"Broadcast message from root Fri Sep  8 17:10:57 2000

The system is going down for system halt NOW !!".

I was the only one logged on that machine, and I sure didn't shut it 
down. The machine then rebooted (although it should have halted).
I tried to catch something in the logs, and the only thing I could 
find was :
in /var/log/messages : Sep  8 17:10:57 www init: Switching to 
runlevel: 0
in /var/cobalt/adm.log : "SQL INSERT command failed
query = INSERT INTO quota (type, total, used, name, percent, free, 
modify) VALUE
S ('quota', '0.00', '4.83', 'vsite', 'inf', '0.00', 
datetime('now'::abstime));
ERROR: ERROR:  Bad float8 input format -- overflow"
via last(1) : reboot   system boot                   Fri Sep  8 17:13

And that's all.

Does any one have any hint of what could have happened ?

Did the watchdog kick in ? Should that have been logged ?

Have the box been hacked ? But would a hacker just reboot a box ?

Moreover here is the first line of top :
  498 root      15   0   988  984   668 R       0 97.2  1.5  32:18 
swatch

This swatch process has almost always been that high in cpu 
utilization. Is it a top bug ? Can this be related to the reboot ?

I also get this message in dmesg :
eth0: Invalid EEPROM checksum 0x3668, check settings before 
activating this device!

And the same for eth1. Note that the card works.

I will happily provide informations to anyone that can help.

Thanks in advance,

PS: OS-update-3 has been applied on the box for now 3 month.
