I am having similar problems with a RAQ3i which has 256Mb. It does tend to
freeze occasionally and it not rebootable from the LCD panel. I have to
power off everytime.

After a reboot only about 70Mb is used, and within a couple of days it has
gone up to 190Mb, and in due course it will hit 240Mb.

I have been looking inside /var/log/messages and /var/lod/httpd/error to see
if there was any clue. I am wondering if it could be someone's cgi.

I had thought about rebooting the machine via a cronjob once a month, but I
am not sure if that will help and it shouldn't be necessary at all.

I had a look in the archives and the freezing issues I found were either
possibly cooling fan related or ethernet port related. I have given the RAQ
more 'air' by removing the RAQ below it. I tried moving the IP address from
the first port to the second, but that screwed up might virtual sites, and I
had to manually edit the httpd.conf file to put the original IP address back
in, after moving the IP address back.

Any info on what logs I should be looking at to figure what is causing the
freeze would be great.
