Application stops working frequently

Troubleshooting

Hi, I installed the last version of Mattermost on an Ubuntu 14.04 server, but periodically the application falls down, and I have to stop and restart it again! (every 2/3 days). Any idea on why?

tnx
Maurizio

Hi @smauz007,

It looks like an issue connecting to your database, which might be down or unreachable.

Can you tell us more about your configuration, are you running Docker on Ubuntu or did you follow the Ubuntu install process?

Hi it33,
I installed mattermost with Docker as described in “Local Machine Setup and Upgrade” for evaluation. May be this version is not the correct one?

thank you
Maurizio

How much memory does the docker instance have? For example the mattermost preview docker images does not run on Amazon’s micro instances (it does weird things when out of memory). You need at least a t2.small or 2GB.
