Strange PHP FPM startup problem / php5-fpm hangs

[Jonas Genannt]

Hi!

I have an strange php fpm startup problem. I'm using PHP 5.3.14 on
Debian Squeeze and all is fine.

I have now updated to 5.3.16. With 5.3.16 the init script hangs.

I start PHP5 FPM via:

/usr/sbin/php5-fpm --fpm-config /etc/php5/fpm/php-fpm.conf

All pools are started and working, but the php5-fpm does not detach:

/usr/sbin/php5-fpm --fpm-config /etc/php5/fpm/php-fpm.conf

and here it hangs. ctrl +c does not work.

strace tells me:
Process 15949 attached - interrupt to quit
futex(0x7fb923e8ce40, FUTEX_WAIT_PRIVATE, 2, NULL

I have also tested 5.3.15 but it has got the same problem like
5.3.16.

Switching back to 5.3.14 and the php5-fpm detach correctly.

So my configuration works great on .14 but not on .15 and above.

Does anybody know that's going wrong here?

Thanks,
Jonas
