Unfortunately udp receiver hangs also without

Will try next without cluster if regular insert would work.
So far no hang when
acc is not using cluster db_url.
Cluster has two connections with mode "5s5s".
If I have understood correctly, underlying db_mysql module is not aware
of the cluster. If so, how could use of cluster cause hang in
libmariadb?
Are the two connections going to the same mysql server? Or different ones?
Are you able to see from the logs if writing to the first connection
failed and it tried to the second one?
db_cluster does some basic operations here, in the way that tries to use
the first connection and if the underlying module returns error, it
tries via the second one. It doesn't do anything specific for the
connector module and the connector module should not be aware of the
db_cluster.
