Hello

I'm facing strange problem. My http://my_ip/phpmyadmin/ showing just blank white page! but all database is working fine. when I restart httpd it loads properly but after few minutes it is showing just blank white page so every time I need to enter phpmyadmin I have to restart httpd first! can any tell me how to fix this? my server has 8gb memory and I set 512mb memory limit in php.ini.

Thanks

It can be several problems... a lot logs say, can you show us error_log? - /var/log/apache2

For debagging, after you see blank screen, try in console:
cd /usr/share/phpmyadmin
php index.php

It may be problem with apc/xcache mod and others... logs, please, how logs )

Hello

I didn't find /var/log/apache2 my OS is cent OS 6.5 64bit. beloww is the last few lines from /var/log/httpd/error_log

No solution? I think there is some easy solution cause everything is ok, after restating httpd phpmyadmin loading fine but sometime later it shows again blank white page. where to increase memory usage for phpmyadmin?

Hello

I'm still looking for solutions. I realize when httpd cpu usage going over 10% and memory over 5000mb it is showing blank phpmyadmin page! any idea?

Is mysql crashing too, or just phpmyadmin? Also what does this error log say? /var/log/mysqld.log

let me know what to do in this situation.

Is here no vestacp expert who can realize my problem!?

At last I have figure it out and what I thought it is a very easy solution! just changed

/etc/php.d/apc.ini

from apc.shm_size=64M to
apc.shm_size=512M

and problem is solved.

Thanks
