Error on couchbase 6

when running “service couchbase-server status” getting the errors :
“epmd[2016]: epmd: got partial packet only on file descriptor 7 (0)”

is it critical?
what it mean?


We also face similar issue. Could you please share how this was solved at your end ?
Our environment is RHEL 7.2, with Couchbase 4.0.
We have a single bucket with very few elements in it. We got this error while flushing the bucket through webconsole.
Would be of great help if you can share on the solution taken.
