I'm getting some very strange PHP-FPM behavior I'm trying to debug.
PHP-FPM works fine for around a day and a half, but then it crashes,
dumping this to the log file:

Any ideas what could trip the assert? I tried messing around with the
max fd's but it doesn't seem like it's fixing anything. I'm running
PHP-FPM with nginx and PHP 5.3.0
