It depends. As far as I know, all those daemons use backends which are
based on Berkeley DB or something like that. To function properly, they
need byte-range-locking on their files. AFS does not support that kind
of locks. You might lose data.
You might try to use large files via loop-back mounts. But I think AFS
is just not designed for that kind of application.
