Description

When we start processes on each of our two business-central nodes at close to the same time (within seconds), we get a "KieRemoteRestOperationException: Unable to commit transaction" error on one of the nodes. The other runs normally. The root cause of the exception is...

Caused by: org.mariadb.jdbc.internal.util.dao.QueryException: Deadlock found when trying to get lock; try restarting transaction
Query is: insert into EventTypes (InstanceId, element) values (?, ?)
Query is:
insert into EventTypes (InstanceId, element) values (?, ?)

        at org.mariadb.jdbc.MariaDbServerPreparedStatement.executeInternal(MariaDbServerPreparedStatement.java:364)
        ... 84 more

We're running with singleton strategy. Both nodes are configured to share the same database instance (mariadb). I've confirmed we're using mysql hibernate dialect.

Is there some other configuration we need? Everything we've seen says the way to cluster is to point both business-central nodes at the same database instance.

Business Central is creating the tables via hbm2ddl on WAR startup.

Here's the full stacktrace...
