Samba 4 beta8 PANIC: internal error

[Ricky Nance]

Hey Steve, can you confirm that nothing is running on the following ports
while samba is not running, 88, 135, 389, 464, 636, 1024, 3268, 3269. I am
not sure about your specific distro but on Ubuntu I can issue the following
command:

netstat -anp | grep '88\|135\|389\|464\|636\|1024\|3268\|3269' | grep -i
listen

If there is something else running that conflicts, that may be the culprit.

If that doesn't work, there is some stuff you can do with tdb backup that
might help, but the instructions are risky and I'd rather not post them on
list, as someone browsing across them later on may miss a step
(specifically backing up the samba directory).
