This is an example repo, to illustrate the serviceNotAvailable error from moleculer .
This test only works on linux like machine (kill need to allow to send specific signals) .
Also, you will need nats (or other message broker) (TCP transporter send disconnect when process die, without waiting the disconnect packet)
Here is the scenario :
- start node1 and node2
- kill node2 (let services to kill them, but exit before transit send DISCONNECTED)
- restart node2 (before the heartbeatTimeout => node1 will just try to update the existing node)
To start this test, you can use npm start, or just run index.js
An easy fix can be to update this function with (tested locally) :
// Update properties
this.metadata = payload.metadata;
this.ipList = payload.ipList;
this.hostname = payload.hostname;
this.port = payload.port;
this.client = payload.client || {};
this.config = payload.config || {};
-this.instanceID = payload.instanceID;
// Process services & events (should make a clone because it will manipulate the objects (add handlers))
this.services = _.cloneDeep(payload.services);
this.rawInfo = payload;
const newSeq = payload.seq || 1;
-if (newSeq > this.seq || isReconnected) {
+if (newSeq > this.seq || this.instanceID !== payload.instanceID || isReconnected) {
this.seq = newSeq;
+ this.instanceID = payload.instanceID;
return true;
}(but I think changing instanceID need to produce some other events ? emit a reconnection ?)
