I am on campus. On my office machine, where I always keep a window on 
nebka, it says:

Message from syslogd at nebka at Sat Mar 15 07:37:41 2008 ...
nebka kernel: journal commit I/O error
Read from remote host nebka.uconn.edu: Connection timed out
Connection to nebka.uconn.edu closed.

On nebka itself, I have error messages I have not seen before. I am not 
putting everything, as I have to copy by hand while switching screens:

EIP is at io_callback+0x1c.0xde [aacraid]

EIP: [<f88ad16.] io_callback+0x1d/0xde [aacraid] SS:ESP 0068:c0315f1c
<0> kernel panic - not syncing: Fatal exception in interrupt.

According to syslog, the last instruction before panic was 
make-repec-per.sh. At the same time, the daily jobs from anacron were 
running (last one looks like sysstat/sa1), possibly also awstats.pl 
(why???)

Note that according to crontab for aras, every hour at 37, there is also 
events_archiving running. I commented it out, as this seems to coincide 
with the panic.

All in all: a lot of things running at the same time, all with lots of 
I/O. If on top of that there in a rsync coming from outside, I can 
understand the machine is panicking.

I am going home now. I have now spent two full days on this. I have a 
report due today and will work on that.
