Last time I saw this was building Flang for Compiler Explorer. In that case it was the build using up all the RAM.

I can't see the previous logs anymore but if it happens again maybe the last few files ninja prints would be a clue.

If Flang is not enabled then it could be CPU use. If you have seen a lot of time based tests time out that's another sign of that. For example lit's timeout and cancellation tests.
