[Samba] error messages

[Martin Smith]

I have a brand new in stall of samba4 on a FreeBSD 10 machine and I am 
getting these messages on the console practically all the time.
I have actually disabled load printer list in globals but it does not 
seem to make any difference, I am not intending to use it as a 
printserver at all, just for files, it is to replace a system which is 
quite old and running out of space
