Builds failing on test-rackspace-fedora32-x64-1

[richardlau]

Looking at https://ci.nodejs.org/computer/test-rackspace-fedora32-x64-1/builds node-test-commit-linux builds are generally failing since around 28 days ago.

Recent failures look to be consistent with running out of memory during compilation:
e.g. https://ci.nodejs.org/job/node-test-commit-linux/nodes=fedora-last-latest-x64/53170/console

10:44:32 g++: fatal error: Killed signal terminated program cc1plus

The machine has 2GB RAM available (no swap):

[root@test-rackspace-fedora32-x64-1 ~]# free -h
              total        used        free      shared  buff/cache   available
Mem:          1.9Gi       215Mi        74Mi        10Mi       1.6Gi       1.6Gi

compared to test-digitalocean-fedora32-x64-1 which has 2GB of swap:

[root@test-digitalocean-fedora32-x64-1 ~]# free -h
              total        used        free      shared  buff/cache   available
Mem:          1.9Gi       286Mi       1.4Gi       0.0Ki       231Mi       1.5Gi
Swap:         2.0Gi       189Mi       1.8Gi

I'll try rebooting the machine for now -- we'll probably eventually end up replacing this machine as part of #3350.

So I did previously add swap to this machine: #2527 (comment)
Sure enough the swapfile exists:

[root@test-rackspace-fedora32-x64-1 ~]# ls -al /swapfile
-rw------- 1 root root 2147483648 Oct 13  2021 /swapfile
[root@test-rackspace-fedora32-x64-1 ~]#

I've enabled swap:

[root@test-rackspace-fedora32-x64-1 ~]# swapon /swapfile
[root@test-rackspace-fedora32-x64-1 ~]# free -h
              total        used        free      shared  buff/cache   available
Mem:          1.9Gi       197Mi        72Mi        10Mi       1.7Gi       1.6Gi
Swap:         2.0Gi          0B       2.0Gi

Builds are passing again on this machine.
