My goal is to implement APC for the opcode cache for the drupal 6 production site. I have so far tested APC with several php files with and without including other php files with include_once.
Also tried setting apc.ini values for shm_size, apc.include_once_override and apc.stat. Each time apache reboots.
The result in apc.php does not show any changes in any values. (except, of course, the modified apc.ini values are shown as they should)
Each time I refresh the apc.php test page, the start time is reset as the current time, showing uptime of 0 minutes.
apc.php -testpage shows:

I followed these steps to determine if suexec settings would affect caching: http://www.litespeedtech.com/support/forum/showthread.php?t=4189
[ root@host /]# ps -ef|grep lsphp root 20402 17833 0 11:21 pts/0 00:00:00 grep lsphp [ root@host /]
.. indicates that lsphp is not working on the host
I also read the following article and comments, concluding that in my case the problem is not suexec, since the apache user is the owner of the httpd process http://www.brandonturner.net/blog/2009/07/fastcgi_with_php_opcode_cache/
also the suexec command is not recognized when registering and running as root @host
I am also pretty sure that there is no cPanel on the host to check if the reset parameter of the running cache process will be on a certain interval
This leaves me with a few tips on where to go next. I tried to install (with chown and chgrp) apache as the owner of the apc.php file and some test php files, which resulted in a 500 server error.
Is there a way to check if file permissions are allowed? I am extremely grateful for any suggestions or help.
