Rocket.chat: Rocket.chat startup exceeds Heroku Boot Timeout

[AntMarras]

Description:

I update from 0.60.4 to 0.62.2 and I started to have
Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch
in heroku when heroku restart the dyno (every 24h). I am running RC in a stardard dyno.

Server Setup Information:

• Version of Rocket.Chat Server: 0.62.2
• Operating System:
• Deployment Method(snap/docker/tar/etc): heroku
• MongoDB: mLab MongoDB Shared Cluster 1GB

Steps to Reproduce:

1. Run on heroku wth stardard dyno and mLab MongoDB Shared Cluster 1GB

Expected behavior:

Should not have such long time to boot

Actual behavior:

Crush on restart

Relevant logs:

Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch

Mhhh... but your server comes up? Or is there any bug that you think might be responsible for that behaviour?

Otherwise I would deem this issue too broad as "starting the server faster" is not just one thing that can be tackled... I suggest that you raise your timeout if possible.

It comes up eventually, by chance after 10-12 reboot.. But Heroku restart the app once a day facing the issue and make the app unavailable.
It is not possible to raise the timeout, Heroku do not allow it.
As result the deploy on heroku via button is not currently working and Rocket Chat cannot be deployed on Heroku. So I would suggest to remove the deployment on Heroku option if fixing this in not in your priority.
I had to roll back on 0.60.4 version.

I see your point... yet I think it's just not possible within one bug to "make the server start faster" ... yes, Rocket.Chat takes its time to come up... but I don't see anything that could be done fast to solve this. My server usually comes up far faster than 60 seconds, thought it's also not in the order of 5 seconds. You're writing, that you're on a shared mongodb cluster. This might also have a major speed impact. I'm not very familiar with heroku, but can you upgrade your tier maybe?

/cc also to @geekgonecrazy: I think I'd like to close this issue as it's not really sometjing that could be acted upon in a specific manner. What's your take?

Depending on the amount of channels, users and subscriptions (users in channels) it can take a bit to start. Let's take for instance open.rocket.chat. it can take up to 5 minutes ;)

This is very dependant on server size, mongo and server speed. If it takes even longer because of slow mongo to populate the cache then also nothing we can really do.

I'd agree issue wise. Nothing here to really act on. If we can narrow down and open a specific issue then we can act

Agree with @AntMarras. We have the same issue w RocketChat on Heroku. We did get Heroku to provide us 180s boot time for this app but still we see error messages on the restart every day. Root cause of long boot time seems that Meteor is rebuild each time from the Heroku buildpack. Seems that could be avoided by having binaries in the buildpack for the Heroku environment (Ubuntu)

Heroku support increased my timeout to 120 seconds but that didn't help with this issue for Rocketchat 1.2.1.

One of the solutions that worked on free tier of Heroku
