What is filling up 4G of swap with inactive pages such that none of them are being freed? The usual case is available memory is well below the watermark before swap has filled. But in this case, it's the opposite. As sigterm is happening, memory available is still dropping. Some process is still taking up more memory, but has low enough badness that its not being terminated. It could be one of the exempt processes. > > Perhaps this ps_mem snippet is useful: > <snip > Private + Shared = RAM used Program > </snip> > .... > <snip> > 294.8 MiB + 4.7 MiB = 299.4 MiB telegram-desktop.bin > 290.3 MiB + 22.1 MiB = 312.4 MiB rocketchat-desktop (5) > 323.8 MiB + 9.5 MiB = 333.2 MiB kwin_x11 (9) > 344.5 MiB + 1.4 MiB = 345.8 MiB nextcloud > 373.2 MiB + 21.2 MiB = 394.4 MiB spotify (5) > 416.6 MiB + 1.3 MiB = 417.9 MiB plasma-discover > 448.5 MiB + 16.6 MiB = 465.2 MiB MainThread > 892.8 MiB + 444.5 KiB = 893.2 MiB packagekitd > 1.0 GiB + 8.6 MiB = 1.0 GiB plasmashell > 1.9 GiB + 81.0 MiB = 1.9 GiB Web Content (9) 892M for packagekit? Seems excessive. I wonder what's up with that. It is an exempt process. On my current system it's 1/2 that amount, which is in turn twice that of GNOME shell. Hmm. > Well I'll report soon, any idea (remember I have 16 GB of RAM with 4G of zram-based swap) will be welcome Very common. The defaults need to serve this use case. -- Chris Murphy _______________________________________________ devel mailing list -- devel@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe send an email to devel-leave@xxxxxxxxxxxxxxxxxxxxxxx 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@xxxxxxxxxxxxxxxxxxxxxxx
