[drupal-support] Large taxonomy hangs server?

[Carlos Rivero]

Hi alvaro! that website looks great!

That is totally weird! .. one of my main reason to moving to drupal a
month ago was that some perl CMS were killing the server and not the
php ones.

The first thing you do is enable throttle which handles the
auto-throttling mechanism, to control site congestion. just to make
sure that we are not querying more than we have to.

while you check your logs I suggest what I was doing when I had those
perl based CMS:

create a cron like: 

0       */6    *       *       *       /etc/init.d/httpd restart

This will restart your server every 6 hours. So while try to find the
problem server cleans it self.

Can you post here your error logs of apache when dies?

BTW! what are you using to show all the content on the 1st page? summary module?
(this could be killing it if is doing a lot of querys wrong)

Que tengas un buen dia! y suerte con los logs!
