To what extent has Cyrus been tested with 64 bit builds? One of my
users has managed to create a mailbox with a >2.0G cyrus.cache, which
of course can't be mmap'd. The mere act of finding out how many
files there are in there is itself a problem: I've got
perl -e 'use IO::Dir; my $d=new IO::Dir("."); while ($f=$d->read())
{ print $f, "\n"; }' | wc -l
running to read the directory without stat-ing anything, but that's
struggling. It's on NAS storage with hashed directories, so it
didn't slow down as it got bigger: the problem probably didn't arise
until the cache directory got too big!
