	Sure: it's a performance problem with locks
	which shows up when locking the index file of 
	a dbm-style database (which have two files, an
	index and a data file), and which is being shared
	via Samba with PC clients. At least one site,
	and probably two, have the problem. I'm following 
	it with considerable interest (I work for Sun, you 
	see, although not on Samba (:-))

	It doesn't affect the performance of Samba on
	Solaris in general, and oddly enough it doesn't
	seem to hit MS Access...

	It's not related to the	problem you see, with ordinary
	oplocked .doc files.  One wouldn't oplock dbm files!
