So, just to clarify and provide more info here: There's a bug/issue with 32bit arm using LPAE kernels and xfs/ext4 where it's overeager with OOM killing processes. ( rhbz 1920183 ). The issue does not seem to happen with > 5.16 kernels and btrfs installs. I had reinstalled some small portion of our armv7 builders this way and they seemed tons more stable from this bug at least. So, I have been the last few days replacing all the last xfs ones with btrfs + 5.16.x kernels. That should hopefully be complete later today or early next week. So, I suspect some of what folks are seeing should go away with this change. Of course other things to keep in mind are that these are 32bit processes, so they are never going to be able to use > 3GB just due to address space. The builders themselves have 40GB memory, so that limit shouldn't be hit, but the address space per thread definitely could be. kevin _______________________________________________ devel mailing list -- devel@lists.fedoraproject.org To unsubscribe send an email to devel-le...@lists.fedoraproject.org Fedora Code of Conduct: https://docs.fedoraproject.org/en-US/project/code-of-conduct/ List Guidelines: https://fedoraproject.org/wiki/Mailing_list_guidelines List Archives: https://lists.fedoraproject.org/archives/list/devel@lists.fedoraproject.org Do not reply to spam on the list, report it: https://pagure.io/fedora-infrastructure
