This testcase seems to be very flaky. With focal/linux 5.4.0-85.95 it failed on the arm64 dazzle node at the following subtest:
08:24:55 DEBUG| [stdout] memcg_stat_rss 6 TINFO: Running memcg_process --mmap-anon -s 135168 08:24:55 DEBUG| [stdout] memcg_stat_rss 6 TINFO: Warming up pid: 640968 08:24:55 DEBUG| [stdout] memcg_stat_rss 6 TINFO: Process is still here after warm up: 640968 08:24:55 DEBUG| [stdout] memcg_stat_rss 6 TPASS: rss is 135168 as expected 08:24:55 DEBUG| [stdout] memcg_stat_rss 6 TFAIL: rss is 135168, 0 expected But with version 5.4.0-83.93 it failed on another subtest on the same node: 18:11:33 DEBUG| [stdout] memcg_stat_rss 1 TINFO: Running memcg_process --mmap-anon -s 135168 18:11:33 DEBUG| [stdout] memcg_stat_rss 1 TINFO: Warming up pid: 632606 18:11:33 DEBUG| [stdout] memcg_stat_rss 1 TINFO: Process is still here after warm up: 632606 18:11:33 DEBUG| [stdout] memcg_stat_rss 1 TFAIL: rss is 0, 135168 expected And looking at other results sometimes the testcase completes successfully. ** Tags added: sru-20210906 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1837035 Title: memcg_stat_rss from controllers in ubuntu_ltp failed To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1837035/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
