             Summary: OutOfMemoryError in MQTT adapter
                 Key: STREAMPIPES-262
                 URL: https://issues.apache.org/jira/browse/STREAMPIPES-262
             Project: StreamPipes
          Issue Type: Bug
          Components: Connect
            Reporter: Philipp Zehnder


When the MQTT adapter is running for some time we get an of memory exception.

I tested it twice for the same setting. The first time the error came after about 5 hours and 3000 events and the second time after 13 hours and 5500 events.
