Kiran suggested that this might be this recent change in MLIR that’s increased build times: https://github.com/llvm/llvm-project/issues/62687

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 it on this bot. We know that that sub-project is tested quite extensively through dedicated Flang bots. What do you think?

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 machine. So I wonder if this could simply be due to insufficient memory.
I will relaunch a few builds to check if something significant changed with last commits.

Hi,
Has anyone noticed that https://lab.llvm.org/buildbot/#/builders/198 (clang-aarch64-sve-vla-2stagehttps://lab.llvm.org/buildbot/#/builders/198) 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 caused by changes to that sub-project (https://lab.llvm.org/buildbot/#/builders/198/builds/1804). Would anyone be able to take a look?
Best regards,
Andrzej
