I tested the following. 
stop winbind 
rm /var/lib/samba/winbindd_cache.* 
start winbind
And the error is gone.
I did notice the following, before and while having the log message. 
running : net cache list | grep username 
That shows the user. 
Now after stoping , remove the cache.tdb files and starting i tested it again. 
net cache list | grep username  
! This did NOT show the user, but ... 
net cache list | grep USERNAME
Does show the user.
wbinfo -u  && wbinfo -g
net cache list | grep username   
And it shows the user again, no errors any more in the logs. 
I cant explain why you ( and i ) see a message : cache_traverse_validate_fn: unknown cache entry 
i dont thinks it was an corruption in the cache tdb database, because this exist on all my member servers. 
imo, it is a bug some, that might have been fixed already. 
I did check in bugzilla, but I did not find any related, as far i can tell.

New subject, 

Samba 4.8.3 after upgrade shows. ( message from Re: [Samba] 
Debian Stretch Samba Packages 4.8.3 available (amd64/i386)) 

cache_traverse_validate_fn: unknown cache entry 

I've checked a few more server. 
I have 1 user on all server with this message. 

net cache flush did not resolve the message. 

Rowland, you any idee? 
It's cache so imo, not so scarry, but it would be nice fix 
these messages in the logs. 
Imo low prio, since everything works fine.
