This is quite strange. I don't have any knowledge about how glibc is
coded, but it seems that after "some time", the problem stabilizes and
all instances of apache translate correctly. Maybe it is that all "old"
instances crashed and new ones have the new .mo file.
Anyway, it is quite weird to have a production server in shuch a weird
state for some hours.
Although I don't know the problems involved here, I would suggest
trying to fix this in new glibc versions, maybe transparently, or maybe
with a simple function call (i.e. domain_refresh) that would force a
fresh load of the text domain.
Regards and thanks for your help.

Or admin has set up Apache to run only limited number of requests in
each child. As your .mo files are loaded after server fork, it fixes problem
too. Only problem is that for some time you sometime get page with
new translation, and sometime with old.

It would be nice. Long running processes are more and more common.

Hi,
does anyone know if it's possible to get the PCRE libraries to support
utf8 encoded strings. A cursory glance at the PCRE source which comes with
php4.2.3 suggests that it can support it, but that this is not enabled by
default.
I'm not a C programmer, but I have a feeling that it may be just a matter
of changing a compile flag to PCRE.
(the motivation for doing this would be to unicode-enable an existing app
which uses PCRE functions).
Would very much appreciate comments from those in the know!
Thanks
