SubscriberMessageReader:read Exception

aaaaaaaa

Hi, I've been trying to setup Solace in Java using solace-java-spring-boot-starter. Was able to publish and subscribe to and from a remote server however, IOException is being thrown a lot of times and it won't stop. I'm not really sure how to trace the issue. Has anyone encountered the same issue?

@Aaron - The App worked fine against a cloud hosted broker. In this instance there was a firewall in the middle dropping the connection
After updating the firewall configuration for the solace ports, it now works.

Some kind of timeout, eh? Is this when it's waiting, trying to retrieve a message when there is none published?

Is it possible to turn up the Solace API logging to DEBUG, usually via a log4j configuration file, or something similar?
