Here we are, 10 days later, and I found it. DHCP of all things. When I changed the default lease time on the DHCP server, the freeze time changed, "coincidentally" to the same value as the lease. Then I found a Red Hat bug report (https://bugzilla.redhat.com/show_bug.cgi?id=1256042) with the same issue and the end result is "it's by design." Ugh. So I changed the default lease time to a week - now no problems. Regards, George Toft On 12/7/2016 8:55 AM, Brian Cluff wrote: > Is there any common storage they all have write access to?
