Hi,
I've got a Dell Dimension XPS B866r desktop running as my web/mail
server (recently upgraded to 3.9).
Occasionally, after a seemingly random amount of time, the machine will
do one of two things: it will either lockup/freeze where there are no
messages on the console, but you cannot type, ping or access the box in
any way (but the reset button) OR, since I have ddb.panic=0, it will
reboot with the following message from my serial console:
panic: semop - can't undo undos
Starting stack trace...panic(fffffff4,3,e870df10,2,fffffff4) at

Since the box rebooted automatically, I don't have ps output, but the
box is running: stock GENERIC kernel, mysql-server-5.0.22, stock apache
(chrooted) w/ ssl, courier-imap/pop3 w/ssl, imap-proxy,
php5-core,curl,gd,imap,mbstring,mcrypt,mysql-5.1.4-hardened (compiled
from CVS ports of -current), wordpress-2.0.3, gallery-2.1.1,
squirrelmail 1.4.6 and 1.5.1, spamd (openbsd), spamassassin
(spamc+spamd+procmail), clamav (clamav-milter + clamd), sendmail (with
sasl compiled in), sasl with mysql+crypt patch applied, pure-ftpd
(requiring ssl... not really used).
When the box comes back up, none of the log files have error messages.
Let me know if I can provide any more info.
Does anyone have any thoughts? I'm thinking that I'm running too much
on my P3-866 w/ 512 MB RAM and should set up another box to offload
either mail, apache or mysql.
Below is a dmesg.
Thanks.
