Description of my

Hi,

since some weeks, my RocketChat service fails every other day and sais something about "

JavaScript heap out of memory

It’s very easy to “solve” manually, by restarting the service.

My questions

  1. do you think that has something to do with the logs before of the mail inbox (they occur often, without the service crashing?)
  2. do you have another idea, that causes it?
  3. As a quick workaround: is there a way to say the service automatically to restart, when it fails? Where would be the service configfile and what is it, I would have to change there?

Thanks a lot for your help!

Best
Valentin

Rocket.chat service file is here: /etc/systemd/system/rocketchat.service

You can add Restart=on-failure in the [Service] section.

edit:
(What are the ram specs of your server?)
