Unfortunately, that hasn't helped.
Version 4 doesn't log the pid of the process accessing the mount point,
so we still don't know what's causing this.

Do you have hald running?
Does this behavior change after an hour or so?

Are there many processes running?
If not perhaps a list of them would help.
