        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.
