close event about slack-bot-api

[Starfox64]

You could call the login() method, it should restart an RTM session.

It usually closes the connection immediately after login. Might there be some limit on number of simultaneous sockets per one user? I do have around 20 bot instances deployed using same credentials.

[Starfox64]

If you suspect that sockets are being closed because of how many instances are running, I would suggest to listen for error events on the socket and look if your sockets are being rate limited. According to the API documentation continuing to send request after being rate limited will get your application disconnected.

They get disconnected even when not rate limited. They really don't talk much - 2-3 messages per hour per instance so total messages are around 40 messages/hour.
From pool of 20 machines about 15 are connected and 5 get disconnected. Machines go down for night and in the morning when they boot up, the situation is similar. Just disconnected machines might not be the same ones.

Your question is how to reconnect or why connection sometimes closes immediately?

For reconnection you can simply invoke login method.
Is second problem connected with this issue #20?

[mitselek]

My question as of today is, if anyone knows why sockets get closed, if there are more than 17 instances of same bot user. I think this should be asked from slack team instead :)
Otherwise login method works as expected and thank You both for this.
