Hello Sean, and thanks for the info. I upgraded to apache2-mpm-prefork 2.2.3-3.2 and PHP 5.2.0-8 since 4 ours and the bad behaviour has not yet happened... That's great, I hope the problem is solved with the latest release. Alex -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Hello Sean, and thanks for your quick reply.

No more, I suspected that could be a problem and I eliminated all symlinks to be sure. otherwise, we'll need some more info, namely dpkg -l '*php5*' and any changes you've made to /etc/php5/apache2/php.ini, and any php related configuration in your apache2 configuration. Here the relevant modules: ii libapache2-mod-php55.1.6-5 ii php5 5.1.6-5 ii php5-cli 5.1.6-5 ii php5-common5.1.6-5 ii php5-gd5.1.6-5 ii php5-mysql 5.1.6-5 Apache is version 2.2.3-3.1, mysql is 5.0.30-1, kernel is 2.6.18-3-amd64. The only change made to php.ini is increased the memory limit to 256M and max execution time to 60 seconds. There are non php related configuration in my apache2 config. also, are you using any .htaccess directives? anything mbstring related? is this a 3rd party web app or your own in-house application/site? It's a 3rd party webapp build only on standard xoops modules, nothing strange or developed in-house. There are a couple .htaccess directive with this content: Options All -Indexes and: order deny,allow deny from all Thanks, Alex -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

I'm sorry I'm unable to find a combination of code/request that triggers the problem, I tried as single user and the site seems fine, but as soon as I open to everyone it's a matter of seconds to have threads that begins to loop and after a few minutes the machine begin to suffer very much. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

hm... are any of the directories between /var and var/./site
symlinks?
otherwise, we'll need some more info, namely dpkg -l '*php5*' and any
changes you've made to /etc/php5/apache2/php.ini, and any php related
configuration in your apache2 configuration.
also, are you using any .htaccess directives? anything mbstring related?
is this a 3rd party web app or your own in-house application/site?
