consul server: Missing check 'serfHealth' registration

[chymy]

Consul server continuously reports the following error:

[ERR] http: Request PUT /v1/session/create, error: rpc error making call: Missing check 'serfHealth' registration
...

it can't recover until it restart.
According to the code, I don't know why reconcilemember didn't execute successfully

Consul info for both Client and Server

consul version: 1.6.2

Hi @chymy,

Can you provide more details on the JSON request body payload that being sent with the create session endpoint call (/v1/session/create)? Is serfHealth being included in the array of checks in that payload?

Is this something that you observe in more recent versions of Consul?

I created it using the consul api (https://github.com/hashicorp/consul/blob/v1.6.2/api/session.go#L72)

I suspect that the node is always in the Leaving state, which causes the reconcilemember function to be unable to execute all the time, as a result, the node serfHealth cannot be registered. For details, refer to serf:#662 and #6882
