[Samba] 3.0rc3 CPU and Memory issues

[Donald Zajic]

Good Morning,

I am currently running 3.0rc3 on a RH9 box and have noticed that my CPU
is pegged to 99-100% continually as well as my memory usage.  I believe
that this has been previously reported; however, I have not seen any
indication of a way to resolve. This is a new install of RH on a P4
2.26Ghz with 768M of RAM.
