Couchbase Server

Hi,

We are facing an issue when we try to enable or disabling the auto failover feature.
Windows 2012 Server R2 (vmWare) 3 Nodes
Couchbase 4.5.1

[ns_server:error,2017-02-23T17:29:45.824+01:00,ns_1@10.174.128.80:<0.29322.5652>:menelaus_web:loop:189]Server error during processing: [“web request failed”,

It’s possible this is related to a bug in Erlang, see https://issues.couchbase.com/browse/MB-7282

Workaround it to run the following -
wget --user=Administrator --password=asdasd --post-data=‘rpc:call(mb_master:master_node(), erlang, apply ,[fun () -> erlang:exit(erlang:whereis(mb_master), kill) end, []]).’ http://localhost:8091/diag/eval
