How to handle stale connection errors correctly?

[LostInDarkMath]

Hi there!

I registered an error callback for the NATS client and I often receive stale connection errors if the client was long time idle (which is expected). My question is: Should I worry about this? How does this library handles this error? Does it a rreconnect and a retry? Or is my data that I try to publish lost?

I took a look as your documentation and your code but I couldn't find out how you implemention works. So I'm looking forward to hearing from you :)
