Node-red Lost connection to server when i use a arduino output node

[tangshuran]

The node name is 'node-red-node-arduino'.
Whenever i use the node in the editor, node-red local server stop working automatically without any warning after a while.
Anyone meet the same problem with me?

Hi, sorry for not responding sooner.

No-one has reported this sort of behaviour before. Is it still an issue for you?

With nothing to go on, am going to close. Please reopen if you are still having issues.
