Out of memory

[dtolnay]

#103 is happening again -- only on play.rust-lang.org, not play.integer32.com. Was adding swap to /etc/fstab expected to fix this long-term? Does it need to be done separately for play.rust-lang.org?

[shepmaster]

Adding swap was mostly to handle the tiny instance size for the integer32.com deployment. The rust-lang.org deployment has considerably more memory, and it appears to have quite a bit free at the moment (1.5+ GB) .

I did see this myself earlier this morning; I restarted the Docker daemon then. I do not see the issue right now.

I wonder if the Docker daemon might have a ulimit or something...

Can't run any code right now

Sandbox operation failed: Unable to execute the compiler: Out of memory (os error 12)

Hmm, maybe that error is coming from the playground executable itself.

I checked the /proc/PID/limits for the server process though:

I've also upgraded Docker just to be on the safe side...
