I'm not sure... tl;dr: seen with kernel linux-stable 5.1.8.r0.g937cc0cc22a2-1 And really not sure if I've seen it before. long read: At least one previous kernel did because I've seen this before in https://bugzilla.kernel.org/show_bug.cgi?id=203833#c1 where I thought it was due to 'teo' governor but it wasn't (I'm using 'menu' gov. now) I didn't mention kernel version there, but according to irc logs where I seek'd help at the time, the date was June 10th 2019 3am, checking which kernel I was running at the time (thanks to my q1q repo. git logs) it was 5.1.8 (stable)kernel to which I updated on Sun Jun 9 10:50:09 2019 +0200 and have not changed until Tue Jun 11 05:16:59 2019 +0200 local/linux-stable 5.1.8.r0.g937cc0cc22a2-1 (builtbydaddy) Side note: I've encountered something similar here https://github.com/constantoverride/qubes-linux-kernel/issues/2 where kworker would randomly start using 100% CPU and couldn't be killed. The kernel there was 4.18.7, the VM had very little RAM in Qubes there. Since it's probably a different bug due to that stacktrace being so different/unrelated, please ignore.

From the trace, it was obvious that the scanner is making no progress. I don't think zswap is involved as such but it *may* be making it easier to trigger due to altering timing. At least, I see no reason why zswap would materially affect the termination conditions. From the path and your trace, I think what *might* be happening is that a fatal signal is pending which does not advance the scanner or look like a proper abort. I think it ends up looping in compaction instead of dying without either aborting or progressing the scanner. It might explain why stress-ng is hitting is as it is probably sending fatal signals on timeout (I didn't check the source). Can you try this (compile tested only) patch please?

I don't know if it matters in this context, but I've been using the term `zswap`(somewhere else I think) to (wrongly)refer to swap in zram (and even sometimes called it ext4(in this bug report too) without realizing at the time that ext4 is only for /tmp and /var/tmp instead! they are ext4 in zram) but in fact this isn't zswap that I have been using (even though I have CONFIG_ZSWAP=y in .config) but it's just CONFIG_ZRAM=y with CONFIG_SWAP=y (and probably a bunch of others being needed too). > > From the path and your trace, I think what might be happening is that > a fatal signal is pending which does not advance the scanner or look like > a proper abort.

I even tried running two in parallel, no OOM-killer. Or this: $ time stress -m 220 --vm-bytes 10000000000 --timeout 30 stress: info: [12381] dispatching hogs: 0 cpu, 0 io, 220 vm, 0 hdd stress: info: [12381] successful run completed in 56s real 0m55.957s user 0m1.908s sys 9m20.969s Longer timeout I could see 65000MiB of swap were used at some point! (in 'top') still nothing triggered OOM-killer :D ok, a timeout of 60 did it(triggered OOM): $ time stress -m 220 --vm-bytes 10000000000 --timeout 60 stress: info: [13225] dispatching hogs: 0 cpu, 0 io, 220 vm, 0 hdd stress: FAIL: [13225] (415) <-- worker 13445 got signal 9 stress: WARN: [13225] (417) now reaping child worker processes stress: FAIL: [13225] (451) failed run completed in 59s real 0m58.812s user 0m2.312s sys 9m53.327s But anyway, since last time I was able to trigger it with the normal(timeout 10) command on the third try, I've decided to keep trying that: after 170 more tries via `$ while true; do time stress -m 220 --vm-bytes 10000000000 --timeout 10; done` I saw no hangs or any runs taking more time than the usual 16-26 sec. So the patch must be working as intended. Thanks very much. Let me know if you want me to do anything else. Cheers! ^ permalink raw reply [flat|nested] 12+ messages in thread

For other bugs, it would matter a lot. In this specific case, all that was altered was the timing. With enough effort I was able to reproduce the problem reliably within 30 minutes. With the patch, it ran without hitting the problem for hours. I had tracing patches applied to log when the specific problem occurred. Without the patch, when the problem occurred, it hit 197009 times in a tight loop driving up CPU usage. With the patch, the same condition was hit 4 times and in each case the task exited immediately as expected so I think we're good. > > a proper abort.

The key was getting a task to receive a fatal signal while compacting and while scanning a PFN that was not aligned to SWAP_CLUSTER_MAX.

Thanks a million for your patience, testing and tracing (the tracing pinpointed exactly where I needed to look -- of 3 potential candidates, only one really made sense). I'll put a proper changelog on this and send it out where it should get picked up for 5.3 and -stable. -- Mel Gorman SUSE Labs ^ permalink raw reply [flat|nested] 12+ messages in thread

Did previous kernels exhibit this > behavior or is it new in 5.2? Is the reason that you switched to email somehow related to bugzilla not even posting this very reply of yours(seen above) that you sent via email even though you included bugzilla in the CC ?! I noticed that only mine got posted and mine was after yours in the emails. Yet there's no trace of yours when looking at the issue through the bugzilla interface. Your (emailed)comment should be right after this https://bugzilla.kernel.org/show_bug.cgi?id=204165#c11 but it's not. Anyway, I'm ready to test stuff, please let me know how I can help. Meanwhile I'll try to find a better way to replicate the issue.
