ccache failure on ARM ODroid - out of memory

ccache: error: x_calloc: Could not allocate 40 bytes

Opening so we can keep an eye on it in case is re-occurs.

Seems to be a persistent problem: https://ci.nodejs.org/job/node-test-commit-arm/12078/nodes=ubuntu1604-arm64_odroid_c2/console

@rvagg can you take a look ?

Still happening FWIW: https://ci.nodejs.org/job/node-test-commit-arm/12177/nodes=ubuntu1604-arm64_odroid_c2/console

Can it be taken offline until it's fixed?

[gibfahn]

Happy to take it offline if it's one machine, but if they're all having this problem then that's not really an option.

The one @bnoordhuis posted was test-mininodes-ubuntu1604-arm64_odroid_c2-2. I've taken it offline, we'll see if the issue crops up again.

ping @rvagg

I've seen g++: internal compiler error: Killed (program cc1plus) a few times recently. Probably the same OOM issue.

I've updated and rebooted those C2 machines. They've been running for a lot longer than they normally do, we tend to have a lot of trouble with them. There were some <defunct> processes on there but nothing taking up much memory that would explain this.

was getting the internal compiler error messages today and it was quite confusing while doing the release, should we take these boxes offline again?
