I'm just setting up a new faster server for our Drupal site and was setting up APC and tried to set the apc.shm_size up to 128M however after restarting apache and reloading the APC Admin page Apache Simply goes away and returns no requests so I started going down till I found 76M was as high as apc.shm_size would go.
Debian 7
APC 3.1.13
Apache 2.2.22
PHP Version 5.4.39-0+deb7u2
APC was installed via pecl
and my apc config from php.ini
extension=apc.so
apc.enabled=1
apc.shm_segments=1
; 76 Max shm_size is taking
apc.shm_size=76M
apc.max_file_size=1M
apc.stat=0
apc.ttl=0
anyone know why it's stopping me from upping it further?
edit: the only error log for apache is
PHP Fatal error: PHP Startup: apc_mmap: mmap failed: in Unknown on line 0
and there are no errors in syslog from apache or php
