unexpected fault address

[amlwwalker]

I am sending data from the host to the plugin and i'm getting a huge crash every so often - after about 4-5 'sends' of data but can be 1 or 2 sometimes.

Anything glaringly obvious?

I have

  rpc PluginEvent(DataMessage) returns (google.protobuf.Empty) {}

in my service (.proto)
and I have a function that is creating a listener for each of my plugins, so that they will fire on an event meant for them.

	for _, v := range a.pluginManager.Plugins {
		eventName := fmt.Sprintf("plugin_frontend_event_%s", v.Info.PluginId)
		runtime.EventsOn(ctx, eventName, func(optionalData ...interface{}) {
			///codes,,,
			byt, err := json.Marshal(optionalData)
			if err != nil {
				fmt.Println("error marhsalling data ", err)
				return
			}
			var receivedDataMessages []interop.DataMessage
			if err := json.Unmarshal(byt, &receivedDataMessages); err == nil {
				fmt.Printf("optional data from frontend %d - %+v", len(receivedDataMessages), receivedDataMessages)
			} else {
				fmt.Println("error unmarshal ", err)
			}
			_, err = v.PluginEvent(ctx, &receivedDataMessages[0])

Where i call PluginEvent is where the crash ultimately happens. I am not sure if its possible to get debugging logs from a plugin at this point to see if anything happened in there:
(thx)
