Dh42 Posted October 1, 2013 Share Posted October 1, 2013 Can you try doubling your output buffering in your php.ini or ask your host to double it. Link to comment Share on other sites More sharing options...
hideo Posted October 1, 2013 Share Posted October 1, 2013 Can you try doubling your output buffering in your php.ini or ask your host to double it. Hi, Thanks for your reply. I tried this first and then I tried to set this value to "On", which is equivalent to "no-limit". That did not change anything. I have this error too, which might be one of the cause: [error] server reached MaxClients setting, consider raising the MaxClients setting. Also, before the site becomes inaccessible, I noticed that the loading time increased gradually. Because of another issue on cms categories, I couldn't activate the cache. Can it be related to my problem? Thanks again for considering my post. Hideo Link to comment Share on other sites More sharing options...

Sure! http://www.laroutedescomptoirs.com I'm on a dedicated hosting, Debian 7 Stable. I've installed: - apache2 - php5 - mysql-server - fail2ban - module memcache(d?) Many thanks for your reactivity!

hideo Posted October 3, 2013 Share Posted October 3, 2013 Hi again, To complete my post, I saw that the CPU is at 100, even if there aren't many simultaneous visits. To make sure that it's only that website on prestashop 1.5.4.1 which causes troubles, I've deactivated only this website and check monitors, it has decreased between 0% and 1%. Enabling the prestashop website again, the CPU immediately increased to 100%! I've seen on this topic (http://www.prestashop.com/forums/topic/244621-154-slowness-a-possible-solution/) that it seems to be related to this version. What do you think about this? Reading the changelog between the 1.5.4.1 and 1.5.5.0 version (http://www.prestashop.com/en/developers-versions/changelog/1.5.5.0), they didn't mentionned anything about the CPU... I think I will try this update and keep you posted if this works better! Of course, if you have any suggestion, I would love to hear them Many thanks, Hideo Link to comment Share on other sites More sharing options...
hideo Posted October 12, 2013 Share Posted October 12, 2013 Hi again, I've upgraded prestashop from 1.5.4 to 1.5.5 but that didn't change anything. But, because of cache problem related to cms categories, I had deactivated smarty cache. After activating this, the CPU load has decreased but it should be between 0% and 5%. Now, it is between 30% and 76%. Still very high but not full! I have an idea where this can come but not sure.. In "blockcategories.php", I've changed the hookleftcolumn function and created several objects to load cms categories. Well, I continue investigating but that's really weird..
