Re: Problem after migrating samba domain PDC from RHEL3 to RHEL4



I think that I found the problem.

If I turn off "wins proxy = yes" , nmbd stays up
if I turn on "wins proxy =yes" , nmbd stop working within
a minute.

I will report this bug to Redhat.

Hi,

I have recently migrated my samba PDC from RHEL 3/i386 to a new server with RHEL 4/x86_64. Sadly, after the upgrade, my samba server failed to work properly, nmbd stop to answer even though the damon stays on most of the time, it did died a few times during my debug sessions. I am using simple smbpasswd
passdb backend.

I see such a line in my nmbd log file.

*** glibc detected *** free(): invalid next size (fast): 0x000000552ad03fd0 *** after that nmbd stop working even though it is still in the process table.

The smbd seems to be okay, as it authenticate Windows users on my domain, but, I just could not connect to other samba file server as the nmbd on PDC dies after a few minutes. The other samba member servers could not talk to
the PDC,
"net rpc join" will fail most of the time (works only when nmbd on PDC is alive briefly)
"net rpc join -S PDC"  always workson .

During the migration, I simple moved /etc/samba directory from the old machine, did I make some major errors by simply doing that? Anyway, I will appreciate to
hear some words of wisdom.  Thank you.
