Thanks, I'll look into that then, as other advantages too ... One thing I just noticed. I use 2 CMF sites under my root (One for each canadian language). When this "hanging" occurs, one CMF site keeps working (French, the less utilized one), while the other one "freezes" ... How could this be ? I remember now having noticed this in the past. Which suggests that maybe this could also be a CMF problem ? Or maybe there are various causes of "freezing" ... (In this case, httpd processes aren't appearing all over the place like I described before ... maybe a similar symptom with a different cause). I'll try the apache+mod_rewrite+mod_proxy see if that helps though ... thanks, J.F. -----Original Message----- From: Dieter Maurer [mailto:dieter@handshake.de] Sent: Thursday, October 24, 2002 3:12 PM To: Jean-Francois.Doyon@CCRS.NRCan.gc.ca Cc: zope@zope.org Subject: Re: [Zope] Problems with restarts, memory usage, DB connections, FastCGI ??

... I have a Zope 2.5.0 (With various products) , running on a custom (But default build) Python 2.1.3 on a RedHat 7.3 ... The machine has a 1GB Ram. I use Apache+FastCGI+Squid.

The symptoms of the problem are as such:

Every once in a while, zope stops responding for a few minutes ... Sometimes it comes back on it's own, sometimes it takes too long and I restart it manually. We have seen similar behaviour (Zope 2.5.1, Solaris 2.5, Apache+FastCGI) as long as we used FastCGI.

We switched from FastCGI to "mod_rewrite" with "[P]" rewrite rules and the problem disappeared. Dieter
