Well, but I don't use multithreading? PHP is running as CLI exec, not compiled into Apache...
That's my configure command:
./configure --enable-pcntl --with-curl --with-mysql
Or do I have to care for thread safety anyway?

After some time however, the parent process hangs; apparently in pcntl_fork(). The child from this fork, however, seems to run normally. An strace on the parent shows "futex(0x471cb0, FUTEX_WAIT, 2, NULL" The program runs on PHP 5.0.3-cli and Linux 2.6. Has anyone an idea what could be the reason for that hang?Didja try: http://www.google.com/search?q=FUTEX_WAIT I did and got: http://lists.boost.org/MailArchives/boost-users/msg07650.php So I'm guessing you didn't compile *everything* on your PHP/Apache system with multi-thread support.
