"More often"??? It has never happened until a few weeks ago.  It is just
in the past few days that it is getting annoying.
We rebuilt all of our filesystems a few weeks ago.  New disks/new
filesystem, etc.  Something about this change is obviously what triggered
it.
I have not found a pattern for why it is happening.  I am not even sure if
it changes from one day to the next or if users just notice it at
different times.  I will keep better track of that.
I will try unmounting,mounting, etc as you suggest.
Thanks
