[Samba] Samba shares freezing

Hey, if you are using Solaris 10, not openSol, you might want to look at
this page. We are using it here at a hospital with some 2k users
(probably a lot less than you, but...) and it's working very well.
http://www.nineproductions.com/technology/1-sun-solaris/3-solaris-10-samba-zfs-configuration.html
One of the things we had major problems with was not having oplocks. As
I recall, they are pretty useful. we have kernel oplocks=yes,
oplocks=yes, but use a fair amount of vetos. This serves as a
fileserver for everyone's My Documents folder. However, we don't use
roaming profiles, so that's probably a blessing on our side there.
Hopefully that link helps you as much as it did us.
