Hi Michael,

Have the same problem with PHP 5.3.

Could you give any advice?

Hi Michael

I downloaded the source code from PECL (http://pecl.php.net/get/APC-3.1.13.tgz) and then:
--
tar zxvf APC-3.1.13.tgz
cd APC-3.1.13
phpize
./configure --enable-apc --enable-apc-mmap --with-php-config=/usr/local/bin/php-config
make
make install

In php.ini
--
extension="apc.so"
apc.enabled=1
apc.shm_segments=1
apc.shm_size=64

The cache is working, however it only lasts for a few minutes and restarts itself. I can see the cache statistics from the apc control panel which comes with the source code.

I have these fcgid options in /etc/httpd/conf/php.conf
--
FcgidMaxRequestsPerProcess 1000
FcgidProcessLifeTime 7200
FcgidMaxProcesses 300
FcgidIOTimeout 120
FcgidIdleTimeout 600
FcgidBusyScanInterval 120
FcgidErrorScanInterval 5
FcgidZombieScanInterval 5
FcgidMinProcessesPerClass 0
FcgidMaxProcessesPerClass 6
FcgidMaxRequestLen 20468982

PHP 5.3.28
