I used /usr/sbin/ab -n 10000 -c 10 <URL> to stresstest it. It crashes after about 3000 requests. Reproduce code: --------------- Start PHP as a FastCGI server. Configure a FastCGI-enabled webserver. Use /usr/sbin/ab -n 10000 -c 10 <URL> to stress-test it. PHP will crash after a few thousand requests. Expected result: ---------------- No crash....
