We've not come across this issue before. it seems, this has occurred in one of the disruptor handlers in Moquette. Shall we enable debug/tracing logs in Moquette side to further drill down the issue,
The following logs will be useful, 1. org.dna.mqtt.moquette.messaging.spi.impl.SimpleMessaging 2. org.dna.mqtt.moquette.messaging.spi.impl.ProtocolProcessor Thanks, Pamod On Thu, Apr 27, 2017 at 6:59 PM, Sumedha Rubasinghe <[email protected]> wrote: > MB guys, > You can consider this as a real production issue.
