PHP Fatal error: PHP Startup: apc_mmap: mmap failed: in Unknown on line 0
[Sun Aug 11 06:45:16 2013] [notice] seg fault or similar nasty error detected in the parent process
The system (Ubuntu 12.04.2) was at 18% of total memory and APC was using 32% of apc.shm_size, so it wasn't for lack of memory. Any ideas what could be going wrong?
I also have these two entries at the same time in syslog
