Hi,
are these interruptions occasionally or do they occur all the time? Is
this a new issue or has this happened before?
Does the openstack environment work as expected despite these messages
or do you experience interruptions in the services?
I would check the network setup first (I have read about loose cables
in different threads...), maybe run some ping tests between the
machines to see if there's anything weird. Since you mention different
services reporting these interruptions this seems like a network issue
to me.
Regards,
Eugen

Just the other day I noticed a bunch of errors spewing from the
mysql service. I've spent quite a bit of time trying to track this
down, and I haven't had any luck figuring out why this is happening.
The following line is repeatedly spewed in the service's journal.
May 08 11:13:47 UBNTU-DBMQ2 mysqld[20788]: 2018-05-08 11:13:47
140127545740032 [Warning] Aborted connection 211 to db: 'nova_api'
user: 'nova' host: '192.168.116.21' (Got timeout reading
communication packets)
It isn't always nova_api, it's happening with all of the openstack
projects. And either of the controller node's ip addresses.
The database is a mariadb galera cluster. Removing haproxy has no
effect. The output only occurs on the node receiving the
connections; with haproxy it is multiple nodes, otherwise it is
whatever node I specify as database in my controllers' host file's.
