Janusgraph Server connection intermittently throws error: not opened at WebSocket.send #95

Closed phani1kumar closed 6 years ago

Getting 'not opened at WebSocket.send' intermittently (say, when the client.execute function gets fired with around 5 minutes gap). Catching this exception and re-inspection the execute method is resulting in timeout error!

I've a firebase cloud function, that gets triggered on some user actions. So, some user actions are failing while others are being successful.

Added a heartbeat query as a discarded promise, but no much use.

Are you positive the remote cluster is up and running? Closing this since it's a bit old, will re-open if further investigation is needed.
