CouchBase Server Out Of Memory (server 4.1.0 community)

I am facing a critical issue that our server sometime will be out of memory and some process will be auto killed. Here is what happened recently.

And more wired thing is, after I add the server back and re-balance servers, all my indexes on that particular server will stop working. Any query with index on that server will return empty result. I have to rebuild all the indexes to make it work again.

Is there someone else experiencing this? Any solution or workaround?


Without logs it’s hard to troubleshoot this but I would recommend trying on 4.1.1 / 4.5.0 CE
