Package: procps Version: 2:3.3.15-2 Severity: wishlist File: /usr/bin/top File: /bin/ps
In some circumstances it is possible that reading /proc/1234/cmdline will hang. I encountered this in a situation where the memory for that file was swapped out and swapping it back in was taking a long time because the process also had a lot of other memory swapped out. It would be nice if ps and top could behave more nicely when the system is in a weird state. For /proc/1234/cmdline I'd suggest a short timeout for reading it before falling back on /proc/1234/comm or /proc/1234/stat* files. -- System Information: Debian Release: bullseye/sid APT prefers testing-debug APT policy: (900, 'testing-debug'), (900, 'testing'), (800, 'unstable-debug'), (800, 'unstable'), (790, 'buildd-unstable'), (700, 'experimental-debug'), (700, 'experimental'), (690, 'buildd-experimental') Architecture: amd64 (x86_64) Kernel: Linux 5.2.0-2-amd64 (SMP w/4 CPU cores) Kernel taint flags: TAINT_FIRMWARE_WORKAROUND, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_AU.utf8, LC_CTYPE=en_AU.utf8 (charmap=UTF-8), LANGUAGE=en_AU.utf8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages procps depends on: ii init-system-helpers 1.57 ii libc6 2.28-10 ii libncurses6 6.1+20190803-1 ii libncursesw6 6.1+20190803-1 ii libprocps7 2:3.3.15-2 ii libtinfo6 6.1+20190803-1 ii lsb-base 10.2019051400 Versions of packages procps recommends: ii psmisc 23.2-1+b1 procps suggests no packages. -- no debconf information -- bye, pabs https://wiki.debian.org/PaulWise
