I've been having problems with Zope failing, resulting in a "Temporarily Unavailable" message when anyone tries to access the site. I was running Squishdot 0.7 on Zope 2.2.x and FreeBSD 3.x. Partly because I was running out of disk space, and partly because of these failures, I've just moved to a new machine with Zope 2.3.2 and FreeBSD 4.3. (In both cases, Apache's serving the http.) I was going to upgrade to the latest Squishdot as well, but ran out of time. The next morning, the failure was back, and it's happened again a week later. All I know is, the threads are still running, but nothing's accessible. If I kill the threads and restart Zope, it works again -- for a while. I haven't really grasped how all this stuff works yet, so: 1) Where to I look for clues (which log files, etc.) to help analyze the problem? 2) Is this a familiar-sounding problem? There was a reference on the Squishdot list to Apache's mod_proxy, but I'm not sure it applies to our situation... Thanks, Michael Sanborn
