[Malvern] php & kernel weirdness on Etch

[Darren Beale]

'lo

I've got a shiny new dev box running Etch and php won't play nicely on
the CLI, scripts will execute, but they don't exit. Initially I
thought it was my code and then I thought it might be the version of
PHP I was using (5.2.5) but I've just freshly compiled a dev snapshot
of 5.3 and even the most simplest command (php -v) hangs after
execution.

Here's the last bit of `strace php -v` which seems to stop in the
middle of futex(...

What's this mean and how could this relate to my issue?

http://en.wikipedia.org/wiki/Futex doesn't mean  a lot to me other
than it sounds kernel related

uname -a gives:
Linux grendel 2.6.18-4-686 #1 SMP Wed May 9 23:03:12 UTC 2007 i686 GNU/Linux

Can anybody suggest what I should try to solve this? Also, sorry for
swearing by saying php (there, I did it again).
