Problems after apache2 graceful with APC

The problem is that after a apache2 graceful the apc won't work correctly. There is an error message in the apache error.log with "cannot redeclare class bughandlerabstract.

Normaly there is a class with this name, but the correct name ist BugHandlerAbstract.

After a apache2 restart it will work again.

I've tried some changes in the apc.ini, but nothing work right now. I tried also to exclude the BugHandlerAbstract.php from apc with apc.filters, but the problem was not solved.

Then i've done a Zend_Session::writeClose(); in our shutdown handler but also not solving the problem.

Here are the settings of the apc:

apc.cache_by_default    1
apc.canonicalize    1
apc.coredump_unmap  0
apc.enable_cli  0
apc.enabled 1

Thanks

I had the same problem in my development box and to be honest I wasn't able to fix it with any proposed solution .

APC is very good but i guess there is no solution to this issue . I guess its bug in APC so I would advise you to convert your cache host app6.xxxxxxxxxxxx.de to xcache and you would be able to convert to it easily in less than 1 hour , so save your time .

Dirk,

PHP 5.3.7 isn't a stable PHP 5.3.1.7 is considered outdated and has known bugs. Running latest stable might solve your problem. Do you get shutdowns and the can't redeclare class error when you run without APC turned on? Whats causing Apache to do a graceful?

Usually with a can't redeclare function or class error it's because the class or function is loading 2 times not because of being cached or not. PHP is pretty smart. Maybe

the apc.filters requires a regex. To exclude the class try:

apc.filters "\BugHandlerAbstract\.php$"

Try changing these sections.

apc.ttl 3600
apc.user_ttl  3600
apc.include_once_override   1
apc.lazy_classes    1
apc.lazy_functions  1
