so on Sep 23rd I made diffoscope run under ionice -n6, and so far the machine has gone down on its knees yet. and on Sep 25th I said this on #debian-reproducible: when i made diffoscope run under ionice i was wondering if there were changes in the linux scheduler causing the probs we saw... now not seeing the machine go down to its knees within 60h uptime i'm saying this to "provoke" the problem coming back however, looking at jenkins.debian.net/munin/static/dynazoom.html?cgiurl_graph=/munin-cgi/munin-cgi-graph&plugin_name=debian.net/jenkins.debian.net/uptime&size_x=800&size_y=400&start_epoch=1661108749&stop_epoch=1695668749 I can that the highest uptime was 15 days.. (since upgrading to bookworm which is when the probs started) it could also be kernel related, with switching to bookworm we switched from 5.10.0 to 6.1.0... so my next stabs c/would be: a.) increase swap b.) upgrade to kernel 6.4.0 from bpo c.) something else Today someone also suggested to use zram to compress swap... and, fwiw, https://tests.reproducible-builds.org/debian/index_performance.html still doesnt look good for yesterday... -- cheers, Holger ⢀⣴⠾⠻⢶⣦⠀ ⣾⠁⢠⠒⠀⣿⡁ holger@(debian|reproducible-builds|layer-acht).org ⢿⡄⠘⠷⠚⠋⠀ OpenPGP: B8BF54137B09D35CF026FE9D 091AB856069AAA1C ⠈⠳⣄ I don't want to see your smile.
