OK, I think I have the smoking gun.
Here is what I see in the log:
[2013/12/17 16:34:08.459496, 10]
winbindd/winbindd_dual.c:1385(fork_domain_child)
fork_domain_child called for domain 'EXCHANGE'
[2013/12/17 16:34:08.460496, 10]
winbindd/winbindd_dual.c:1438(fork_domain_child)
Child process 15002
[2013/12/17 16:34:08.460496, 0]
winbindd/winbindd_dual.c:1430(fork_domain_child)
adding 0x803358760 to list at 0x80330b100
then a little while later:
[2013/12/17 16:39:07.843301, 10]
winbindd/winbindd_dual.c:1385(fork_domain_child)
fork_domain_child called for domain 'XCHANGE'

PANIC (pid 14996): duplicate!
It seems that there are two domains with similar names and winbindd is
treating them the same:
Here is what wbinfo -m shows me:
...
EXCHANGE
XCHANGE
And here is what happens if I try to get info on those domains ...
[xxxxx]# wbinfo -D EXCHANGE
failed to call wbcDomainInfo: WBC_ERR_DOMAIN_NOT_FOUND
Could not get domain info
[xxxxx]# wbinfo -D XCHANGE
Name : XCHANGE
Alt_Name : xchange.some.dom
SID : S-1-5-21-782252399-1160315966-1364796038
Active Directory : Yes
Native : Yes
Primary : No
How can I find out more about that similarly named domain?
