Sounds like a descriptor leak to me.  On one machine here at
UM, the fileserver that's been running several days only
has these descriptors open:
	fd/0:           character special (0/0)
	fd/1:           ascii text
	fd/2:           ascii text
	fd/3:           socket
	fd/4:           socket
	fd/8:           socket
When opening files, the descriptors are generally kept around
and used only inside the one RPC; no reason they should pile
up past that.

Have you looked to see what the open descriptors point to?
