We check error log after our server crashed, and we found that php heap
memory is out of limit,
so I think imagick use emalloc to allocate php heap memory, to check the
zend_memory_usage is
not a method for imagick, other circumstances which occupy huge memory can
use this method to
ensure the system have enough free memory.
