SOLVED v58 to v60 Upgrade and now "Failed to fetch zone:" error

I had 2 of my 3 servers update to v60 over the weekend and now when I try to "Edit DNS Zone" on either of them it says "Failed to fetch zone: domain.com.db"

If you go into their cPanel and they the "Advanced Zone Editor" you also get a "Failed to fetch zone file for domain.com"

Looking at the error log in /usr/local/cpanel/logs/dnsadmin_log I find the following error
"Undefined subroutine &Cpanel::PwCache::init called at /usr/local/cpanel/whostmgr/bin/dnsadmin line 1136."

Everything is still working fine and DNS lookups are good ..... just can't edit them via WHM or cPanel at the moment.

 

No the server is not part of a cluster. And yes all the files do exist in /var/named/
IE: /var/named/example.com.db

They all exist in /var/named/cache as well

I should have mentioned that I am using BIND as well

Was there a naming convention change in the update? Should they all be domain.tld.db?

Sorry for no follow up and the lack of details in this follow up.

I contacted my hosting company for this one and they ended up "resetting your DNSadmin and DNS Clusters"

Turns out they did have some DNS clustering going on to update their own nameservers, though I am not sure if that had anything to do with my problems.

I do not know exactly what they did as I did not have time to ask for details.
