Trouble starting hivemq

1

Hello,

I am receiving the following error. I have confirmed that port 1883 is not in use. How can I resolve this? Thank you in advance!

ERROR - An error occurred while opening the retained_messages persistence. Is another HiveMQ instance running?

Hi rvma,

welcome to our community! This error occurs when another instance is already running. Troubleshooting starts with answering the following questions:

  1. What did you actually check / run /do to confirm this: “I have confirmed that port 1883 is not in use”?
  2. What does the ps -ef | grep java command return?
  3. What does the jps command return?

Kind regards,
Dasha from HiveMQ Team
