[Samba] Ugrade from 2.2.8a to 3.0.2a fails with "PANIC: internal error"

[Michael Keightley]

Tried to upgrade our Solaris 8 domain controller from Samba 2.2.8a to Samba
3.0.2a.  I get loads of errors in the log files then "PANIC: internal error".
I removed all files in var/locks before upgrading.  Below is what is in
log.nmbd.  Any one got any idea what is going wrong?

[2004/04/20 10:33:07, 0] nmbd/nmbd.c:main(664)
  Netbios nameserver version 3.0.2a started.
