Graham,
Thank you again for the help - as you might have guessed, my separate
question that you answered on the mod_wsgi list was because I'd decided
to try out the WSGI solution to the problem first.
What's very strange is that although I did get the same crash when I
first tried running up Apache + PHP + mod_wsgi as I had with mod_python
- as you would expect - it now works fine! I *think* that the change
that fixed it was when I ran apt-get remove libapache2-mod-python - but
I'm not quite sure why that worked.
So I'm now in the uncomfortable position of having a server that works
perfectly well, when I'm pretty sure that it should not. One
possibility: I'm using PHP5, and although the Django page [1] just says
that there can be problems with PHP, the mod_python description of the
bug [2] in one place refers to PHP4 - so perhaps the problem wasn't with
PHP in the first place, but was instead some kind of mod_python version
incompatibility.
Anyway, for now I'll leave this alone and just keep an eye on it in case
things start going wrong again. In case it's of any interest, here's
what I got when I checked the MySQL library versions in the current
working setup:
-------------------------------
# ldd /usr/lib/python2.4/site-packages/_mysql.so | grep mysql
libmysqlclient_r.so.15 => /usr/lib/libmysqlclient_r.so.15
(0x00002b8df7860000)
# ldd /usr/lib/apache2/modules/mod_*.so | grep mysql
# ldd /usr/lib/php5/20060613/* | grep mysql
/usr/lib/php5/20060613/mysqli.so:
libmysqlclient.so.15 => /usr/lib/libmysqlclient.so.15
(0x00002b8f8bd3f000)
/usr/lib/php5/20060613/mysql.so:
libmysqlclient.so.15 => /usr/lib/libmysqlclient.so.15
(0x00002b28d2295000)
/usr/lib/php5/20060613/pdo_mysql.so:
libmysqlclient.so.15 => /usr/lib/libmysqlclient.so.15
(0x00002ba328e47000)
