Getting back to the comment
https://github.com/apache/activemq-artemis/pull/3204#issuecomment-698902202
I've now run our Artemis cluster with updated datasource / connection pool
configuration (forced idle connection eviction after 30 minutes) for a couple
of days. The random reboots have disappeared, so I'm concluding this really was
an issue where our database server is dropping connections. The same fix
(eviction runs) has been in use with other applications using the same database
with similar results, so I'm quite confident with my conclusion.
Additionally did a commit for fixing the datasource pool size as unbounded
as default.

> Improve JDBC connection management

> I have a case where the whole clustering reliability and HA must rely on HA
> capabilities of clustered database, and running on top of application server
> is not an option.
> The current JDBC store implementation is rather bare bones on the connection
> management side. JDBC driver is used directly with no management layer. At
> startup, the broker just opens couple of direct connections to database and
> expects them to be available forever. This is something that cannot be
> expected in HA production environment. So, similarly to the discussion linked
> below, in our case we lose the db connection after one hour, and all the
> brokers need to be restared to get new connections:

> This is something that could be resolved by simply using JDBC4 isValid
> checks, but proper connection handling and pooling through datasource would
> be preferrable.
> I have implemented a solution for this by using DBCP2 datasource. Our test
> cluster has been successfully running this forked version since the release
> of Artemis 2.13.0. I will prepare of pull request if this is seen to be
> something that can be useful.
