This was due to the build-farm running on HEAD with a config including debug_parallel_query=on, which adds a lot of strain on the machine I guess? As this is a single-node VM, I guess it overloaded it regularly. I reported that and I think this is something that needs to be addressed, but people are working on similar issues right now[1]. Is removing the debug_parallel_query=on configuration for HEAD a valid mode of operation for a buildfarm animal? I ran the tests 10 times in a row without issues today.
