Hi Vladimir,
thanks for your reply.
I'll do some more tests then (like decreasing the cache.size until
it no longer fills up the tmpfs partition).
Either way the documentation is a bit confusing to me
because it says it sets the maximum but the maximum is just a
hint that might get ignored.

thanks,
