[Samba] winbind service panics "randomly"

Hi Rowland,
thank you for another quick reply.
1) I did all the changes on the smb.conf you suggested and restart
samba-ad-dc on both DCs.
2) Changed file server log to 10 and rebooted it just because.
3) Winbind crashed.
3.1) I have a gut felling that if I leave it alone, it lasts longer. If I
do a wbinfo -u it's ok, but if I go and check it often, it eventually
crashes. Again, gut felling, maybe it's just a bad dinner. I'll try to find
a way to automate this.
4) wbinfo --group-info="Domain Users"
EUROHIDRA\domain users:x:10001:
5) Don't really know what to look for in the logs, but I can't see anything
clearly wrong. Any tips for things to look for? Log 10 is, well, verbose...
I think I didn't overlook anything obvious, but still
6) Here's the last seconds of the log before winbind panicked.
Anything else?
Best regards
Carlos
