> Key: JAMES-3290
> URL: https://issues.apache.org/jira/browse/JAMES-3290
> Project: James Server
> Issue Type: Improvement
> Components: rabbitmq, SpoolManager & Processors
> Reporter: Gautier DI FOLCO
> Priority: Major
>
> In the distributed flavor, we rely on *MailLoader* which itself rely on
> Cassandra.
> Since this code mix-up reactive and non-reactive code, Cassandra errors are
> non handled which break in the RabbitMQ part:
> {code:java}
> Caused by: com.datastax.driver.core.exceptions.NoHostAvailableException: All
> host(s) tried for query failed (tried: cassandra-0
> (com.datastax.driver.core.exceptions.OperationTimedOutException:
> [cassandra-0] Timed out waiting for server response), cassandra-1
> (com.datastax.driver.core.exceptions.OperationTimedOutException:
> [cassandra-1] Timed out waiting for server response), cassandra-2
