I found the problem with the list configurations.  The issue had to do 
with an in-house patch we developed for 5.4, which was applied to 
6.0.1.  The patch added admin::update_list to the DoFile subroutine.  It 
was added to initiate updates of lists with our LDAP directory before 
distributing messages to its members.

It appears that admin::update_list refreshes the admin_table entries for 
the list by clearing the entries and adding them back. Every so often 
(about twice an hour) this would coincide with the task_manager 
accessing the same list where it would find the owner entries missing 
and change the status of the list to error_config.

The patch was removed and we no longer see any problems with the list 
configurations.
