thx again falko, I know that there is a fix for that error, but my php has stop working completely, My forum stop working and can't load any php page, I don't see any error it just stop working

No error in your Apache error log when this happens? Not even something like this? [Mon Jul 30 14:16:12 2007] [notice] child pid 1827 exit signal Segmentation fault (11)

well yeah, I don't know what that means that's why I posted it, did a search couldn't really find anything, and didn't think that had anything to do with php because that has always been in the log same with the json one, But its ok I will figure it out on my own like I always do, thanks for the help :) .

You can install monit on your server (make sure it's a recent version that can parse log files) and then tell it to restart Apache whenever it finds something like Segmentation fault in Apache's error log.
Something like this in /etc/monit/monitrc should work:

check file apache_errorlog with path /var/log/apache2/error.log
if match "exit signal Segmentation fault \(11\)$" then exec "/etc/init.d/apache2 restart"

lol thanks again, but I already have it installed and working perfect. But I will try and add that line. See I know that php is running when I restart the machine its fine but then its stop working it takes soooo long for the page to open if it even opens, and then I notice a huge spike in memory but can't seem to find whats eating the memory and apache takes 99% cpu, Its not that great of a machine, and its only got 256MB ram, but everything was working great before.

OK I have figured that it must be apache, When ever I try and load a php page
30091 www-data 25 0 63820 30m 1884 R 99.3 12.3 0:11.17 apache2 runs like normal but it takes (R 99.3) of the cpu and I don't know why.

Maybe it's a bug in one of your PHP applications that causes Apache to use so many resources?
