I have had the same thing happening on three servers running 2.0.0 
alpha4 and had to reboot two of them.  Crash dumps showed that they
were 'running' 2300+ nmbd processes...   The third machine had only
been running 2.0.0-alpha4 for a few hours without many connections and
I could stop samba in time.

After some experimenting, I am now running with the following setup:
nmbd -> nmbd-1.9.18p4_ntdom
smbd -> smbd-2.0.0-alpha4

It works fine for now, but are there any consequences of running different
versions of nmbd and smbd?

My configuration:
Servers: Solaris 2.5.1 and 2.6 Sparc's running as PDC's
Clients: mix of NT 4.0 SP3, NT 3.51, W95.
