Lost connection to server at

I keep getting following message after couple of hours of server running.
Database is running locally on Mac OS.

Couchbase Lost connection to server at

The only option is to restart the database.

Is there any parameter that needs to be adjusted?


Hi tushar,
Thanks for using our product. I have questions before answering your issue.
Here are my questions:

  • What is Couchbase server version you installed?
  • Your mac os version
  • What services you set them up in your cluster?

Can you also add the logs if possible

Hi Thuan:
Here are the versions:
Couchbase - Version 6.0.1(6.0.1-2037)
Mac version - macOS Mojave version 10.14.5
Under setting I see: Data (6454 MB), Index (1024 MB), Search (512 MB), Eventing (256 MB), Analytics (1850 MB).

Thanks Tushar,
For Alice (6.0.x), we do not support Mojave. Only High Sierra, Sierra and El Capitan as in this document
If you have any more question, drop me a line at thuan at couchbase dot com

Ok, thanks!
I will use other supported platform.
