What can be issue, nothing more in log in debug mode Can I just backup kahaDb and delete all file inside kahaDb and restart it ?

Please suggest what to do, Its prod server and we have big issue.

  • If the broker won't start it generally always tells you why, search the logs – Tim Bish Oct 01 '17 at 17:19
  • I searched that, but there was nothing, but it could be that it is taking time as data is huge, may be it will start in some hour, I waited for 15 min. – Arvind Oct 02 '17 at 04:24

If you delete kahaDB the contents of your queues and topics will be gone. If you do not care about them - delete it. It will most likely render your broker usable again.

You should have tried to get rid of old messages in the first place. They use a lot of resources. A message broker is not a database.

You could also try to restore your kahadb on a much more powerful machine.

I assume monitoring of your production environment was faulty or non-existent. So you should invest in that area, too.
