Description:
------------
PHP Fatal error:  PHP Startup: apc_shm_create: shmget(0, 134217728, 914) failed: Cannot allocate memory. It is possible that the chosen SHM segment size is higher than the operation system allows. Linux has usually a default limit of 32MB per segment. in Unknown on line 0

PHP Fatal error:  PHP Startup: apc_shm_attach: shmat failed: in Unknown on line 0
[Mon Jun 20 00:00:02 2011] [notice] seg fault or similar nasty error detected in the parent process

[localhost ~]$ sysctl kern.ipc.shmmax
kern.ipc.shmmax: 134217728

Ever since http://pecl.php.net/bugs/bug.php?id=22688 was fixed, every Sunday at 12am PST the server does a graceful restart of apache. When it does, the error above shows.

I've always had shared memory set to 128mb since installing FreeBSD - I've never had an issue until the latest patch.

Upgrading to FreeBSD 7.4 solved this issue.

On php70w-fpm from remirepo on centos, if installed yum install php70w-pecl-apcu, and it have the same error as listed here. But then as well i have php70w-pear installed. And after I do pear upgrade, my php-fpm starts up and all those errors are gone. :-)
