hey,
I only saw the problem under SLES9 meaning 2.6.x kernels, but I think it
is a but in the glibc ( have to lookup the version... ), so you might
also see it with 2.4.x kernels.
It you look at your system with strace when it hangs, you will see the
following:
- there will be one process / thread in a select system call answering
new connections
- all other threads will be blocked in a futex() syscall
For MySQL you have 2 options to resolve this:
- use a MySQL binary ( or recompile ) without pthread support
- disable pthreads by setting LD_ASSUME_KERNEL=2.4.9 or renaming
/lib/tls to s.th. different
For Apache I only know about disabling pthreads as a solution.
cheers
Andreas

.. just curious:
are you running on a Linux box with 2.6.x kernel ? If yes, then you
might have the trouble we had with apache AND mysql and pthreads.
Solution: just move /lib/tls to s.th. like /lib/tls.save and restart
mysql and apache -> solved.
If anyone likes, I can give more input.
Im running linux, but it appears the kernel is 2.4:
$ uname -r
2.4.30-grsec
Thanks for the tip, though!
