LLVM buildbot timing out

Hi, Has anyone noticed that https://lab.llvm.org/buildbot/#/builders/198 (clang-aarch64-sve-vla-2stage) has been timing out for the past few days? "Duration" is often less than 1hr, so that's odd. And all Flang buildbots are green, so it's unlikely

Re: LLVM buildbot timing out

Yeah sure, I am looking at this. Here the timeout happens after 1200 seconds without any new output on stdout/stderr. I reproduce the issue on tcwg-g3-01 with -j34 (the default on this machine): the build is stuck near the end when building flang objects. The same build succeeds using -j16 on this

Re: LLVM buildbot timing out

Thanks for looking into this! Based on the logs and your experiment, looks like it's Flang's fault. 64GB used to be sufficient, but perhaps that's no longer the case (sadly, Flang has insane requirements). I will ask internally. If this is indeed Flang's fault, I'd be tempted to simply disable
