Memory is running out and Discourse stops working


(Dean Taylor) #1

I like many existing users I have been experiencing a combination of these issues:

  • Low memory errors
  • ImageMagicK message in admin panel.
  • White pages / instability

This post / topic is a dump of available information before I restart the instance - so it might help track down the problem.

###System
2GB Digital Ocean instance with 2GB Swap - single site running in Docker.

###History
Earlier this week I restarted my Discourse instance using ./launcher restart app to resolve my then availability issues.

Current version: Discourse 1.2.0.beta6 - https://github.com/discourse/discourse version 8689c85b54efccbccfa216c800522e5ba1a79dd1

###Possible related reports
These are only noted here for there similarity and may not be the the same issue!


###Digital Ocean graphs

###Pingdom uptime graphs

Still collecting information and will continue to post in this thread.


Internal server error while loading admin users page

I believe ruby / some processed restarted not long after I logged into the shell and the site became “more available” displaying pages:

Okay, this is multiple ENOMEM reports in a day. Something with our memory usage has gone up.

confirmed, will find the leak and plug it.


I'm getting a Server Error 500, and have no idea why
Internal server error while loading admin users page

Seems this looks like it has been confirmed as a bug - I’ll change the category.

Feel free to change it back.

Hm, it seems redis is taking up a higher percentage of real memory?

Perhaps Redis is getting extra keys gunking it up? That don’t expire properly.

What’s the general theme of the output of this command?

./launcher enter app
redis-cli INFO
redis-cli KEYS '*' | awk '{print $1}' | sort
redis-cli KEYS '*' | awk '{print $1}' | wc -l

Obviously I have restarted the instance now so not sure how useful that info will be.

No longer at console. Will run when can, atleast 4 hours time.
