[Bucardo-general] 5.6.0 double free in VAC on CentOS7 (continued)

[Jeff Ross]

Not sure that's going to help--or maybe this is another issue.

Getting this in the logs now:

(18916) [Tue Mar 31 11:37:32 2020] KID (load_sync) Warning! Aborting due 
to exception for metro.load_events:? Error was CTL request
(18916) [Tue Mar 31 11:37:32 2020] KID (load_sync) Kid has died, error 
is: CTL request Line: 4997
(24401) [Tue Mar 31 11:37:32 2020] KID (load_sync) Warning! Aborting due 
to exception for metro.load:? Error was CTL request
(24401) [Tue Mar 31 11:37:32 2020] KID (load_sync) Kid has died, error 
is: CTL request Line: 4997


bucardo status shows it moved on from the load table to the load_events 
table but I don't think the load table ever synced back up.
