Ran the up2date on one of my Fedora 2 hosting machines and saw that samba has a new release 3.0.6.
Upgraded without any problem and also the throughput from the windows machines to this little box seemed to be faster or it could just be me imagining it.
I did have an odd problem where from time to time the windows drives mounted on the linux boxes seemed to hang. This appears at first look to have now gone away. Also the memory seemed to clock up really fast on the older version of Samba 3.0.5 and this doesnt seem to be happening, the memory is going up like there is a leak but much slower.
My linux machine is a mini-itx v800.
