If using php-fpm as 'php type', reduce client/customer amount. It's because php thread depend on how much client/customer amount. Better using 'admin' for all your domain and no other clients/customers.

If I switch to php-fpm I can`t change upload_limit_size and post_max_size per domain.

Maybe a bug? i don`t know. the changes a written in the .htaccess but simply they don`t work.

Only if php-type: mod_php_ruid2 is selected I can change the upload_limit_size and post_max_size...

Here are the results of a simple test:

Using: php54 with mod_php_ruid2

The below test is executed from separated machine!

The requested Website test.domain.com is Joomla with no plugins... only few pictures and text... nothing heavy!

OK...

24 hours latter update:

After couple of tests i`ve increased the Memory Limit from 128 to 256
So far so good... All sites are stable and non of them disappear up to now.

But this leads me another problem... with the above configuration the performance of the websites/apache are super slow.

The response time and the actual load of the website...

Please check /var/log/httpd/error_log
If all sites can't load 100% you will see some errors inside error_log.

No errors at all!

OK

After the slow opening of the sites i`ve tried:

./fix-all - no effect
./restart-all - no effect

Total restart ot the system has back to normal everything...

I`ll report back.

It's crazy set 'memory limit' until '512M'. Remember, if want '512' you must set '512M' (that mean '512 MB').

I`ve change it to 128M and now all site are opening extremely slow... maybe i have to restart the services?

37
Kloxo-MR Technical Helps / Re: Serious Problem MRatWork

Try increase 'Memory Limit' in 'Advanced Php Config' from '64M' to '128M'.

Together with it, disable plugin in your website application (like plugin in wordpress) first and then enable one-by-one.

I can increase 'Memory Limit' to 256 or even 512 if it is not a problem i don`t mind...

I will try your suggestion and will report back!

The problem is that no matter what i do and no matter how many times i reinstall the server there is one specific problem which drives me crazy...

After 16 hours up time all the sites hosted on kloxo suddenly vanish... and by vanish i mean that they are not opening in browser.... no matter if there is some application installed on the domain or not the website is not opening.

Only Kloxo Panel is working and i can login.

I have to manually execute sh /scripts/restart-all in order to resolve the issue.

There are no error messages recorded in the logs which is like a ghost living in my server...

Despite the above mentioned problem Kloxo and all related services are working like a charm.

But I can`t restart the server every time the websites are gone and can`t open from browser....

2 weeks already every couple of days i reinstall the server with some hope that this time the problem will disapear..., but nooooo.

Here are some details you`ll probably ask for:

« on: 2014-01-07, 15:15:10 »
I think segfault issue related to how program (let say wordpress) use php. No segfault for this forum.

Better disable all plugins in program and test one-by-one.
Thanks for your support MRatWork!

What about my Problem no.2 above?

Problem No.2

If i change the Php Type to mod_php_ruid2 everiting seams ok but few minutes latter all sites disapears... no log info, no errors ... nothing... i`am executing: /scripts/./fix-all and afterwords /scripts/./restart-all and nothings happends.... the domains are unaccessible even if they respond to DNS ping etc.

All services are working but not really....

I am not really sure if it`s related but when Php-Type: php-fpm_event is selected non of the changes for Advanced PHP Config per domain is applied.

Only when Php-Type: mod_php_ruid2 is selected the Advanced PHP Config per domain is working.

Mustafa,
I report this segfaults long time ago :)

Segfault + (9)Bad file description = PHP-FPM crash (sometime on high load server)

I see the same error in /php-fpm/error.log
