http://bugzilla.opensuse.org/show_bug.cgi?id=1165535 http://bugzilla.opensuse.org/show_bug.cgi?id=1165535#c14 --- Comment #14 from Ulrich Windl <Ulrich.Windl(a)rz.uni-regensburg.de> --- I was able to reproduce the "freeze": I had a top running with a sleep delay of 0.2s, and shortly after starting my test, to became slow and slower until it finally stopped any output. Then the system did not accept any more commands. -- You are receiving this mail because: You are the assignee for the bug.

http://bugzilla.opensuse.org/show_bug.cgi?id=1165535 http://bugzilla.opensuse.org/show_bug.cgi?id=1165535#c13 --- Comment #13 from Ulrich Windl <Ulrich.Windl(a)rz.uni-regensburg.de> --- Created attachment 842196 --> http://bugzilla.opensuse.org/attachment.cgi?id=842196&action=edit Screenshot with top running when freeze occurred (In reply to Miroslav Beneš from comment #11) > Frankly, I am not sure what to do here. It would be too easy to blame it on > HW incompatibility, which Sebastian mentioned. Counter-argument: On a completely different and new hardware (Machine with four Xeon Gold (72 cores, 144 threads, > 700GB RAM) I had a kernel "freeze" while performing some memory load test that just uses a few processes that shuffle process-local memory around. The machine in question only had SSDs, configured as two RAIDs via PERC: RAID1 for base OS, and RAID6 for additional data. When performing the test without having any swap configured, the kernel started to use the OOM killer to terminate a few processes. After having configured 5GB swap @ prio=4 and >700GB swap @prio=2 the kernel froze shortly after having used swap. The special thing about the new setup was that the bug swap was configured via LVM and a thin volume. The kernel in question was 5.3.18-24.15-default (actually from SLES15 SP2), and there was plenty of swap space available when this had happened. Interestingly the kernel still responded to PING, but that was all: No VT-switching, not console getty, no ssh connection, no reaction on existing SSH connections. However I had a "top" with sleep time 1s running at the moment when the kernel froze. I gave it more than 10 minutes to recover, but nothing had happened and there was no message in /var/log/messages after the date top last had refreshed. -- You are receiving this mail because: You are the assignee for the bug.

[kernel-bugs] [Bug 1159882] Excessive swapping when buffers / cache expand beyond free physical RAM
by bugzilla_noreply＠suse.com 01 Oct '20

http://bugzilla.opensuse.org/show_bug.cgi?id=1159882 http://bugzilla.opensuse.org/show_bug.cgi?id=1159882#c57 --- Comment #57 from Robert Delahunt <radelahunt(a)gmail.com> --- Nevermind, I re-checked and saw the date stamp was 25 September, so I reinstalled (what should be) the new kernel. Here are your new vmstats: http://www.puresimplicity.net/~delahunt/vmstat/mhocko2/ I have 32GB of RAM now but still it dug into about 20 MB of swap, even with swappiness=1. Changing swappiness to 60 during this operation didn't seem to influence how much swap it was using, as it still hovered around 20MB or so. It does this both with a file operation (copying large files to an external 512GB SSD in an enclosure) or zeroizing this drive when finished (dd if=/dev/zero of=/dev/sdc1 bs=4K count=1024 etc) I noticed that running sync after the file copy operation dug into swap, i.e. after terminating the copy command, took a long while. Please advise. -- You are receiving this mail because: You are the assignee for the bug.
