If my memory serves me, Exit 137 means out of memory.
Add more RAM and/or increase swap. You likely need at least 5GB of swap+ram.

That’s very strange. 137 does mean that the job received a SIGKILL, which usually means out of memory.
It doesn’t make sense with that much memory, though.

It is strange.
Perhaps check the output of
`sysctl vm.overcommit_memory`

@Ed_S
I noticed that when the memory usage exceeds 1GB+, the process gets killed quickly.

Thanks… It’s still a bit of a mystery to me. But I would strongly recommend running with overcommit. You can set it now with
`sudo sysctl vm.overcommit_memory=1`
but to set it also on reboot might take a little more effort. It may make everything work, in which case making it persistent is the right thing. It looks like I did it by making a one-line file:
```plaintext
# cat /etc/sysctl.d/90-vm_overcommit_memory.conf
vm.overcommit_memory=1
```
If that doesn’t help, it feels like some watchdog or quota is looking out for resource over-use and killing processes. Possibly a good look at the full dmesg output will help - if you’ve recently had the failure, perhaps the last 100 lines might give a clue.

(it’ll hit tests-passed in the next ~30 mins) When testing with a memory-constrained docker container locally, I can now get a successful build with -m 1600m. Before this change, the minimum I could achieve was -m 3000m.
