The Common Lisp Directory (http://www.cl-user.net) lisp process crashed
yesterday after 823 days of continuous service.

In these 2 years and 93 days, the same lisp process (LispWorks on Linux
Debian) served 273M requests without any problem. Even the crash was not
really lisp's fault as it was caused by a swap disk problem which caused the
kernel to kill a lot of processes.

During these 823 days, I had to restart Apache every few months and the
firewall router every several days. I also got several electric power
outages but fortunately none longer than the 3h of UPS battery time.
BTW this shows than Debian is also a stable platform for this kind of
applications.

So the CLD lisp process uptime experiment is now over and I will move the
CLD to a better place than a simple server in my basement.
