I also find it useful to dedup tasks with the same stack trace. The stack1 script attached does this on a running system: $ sudo ./stack1 1 systemd 363 systemd-journal 377 systemd-udevd 530 systemd-timesyn 534 systemd-resolve 594 dbus-daemon 615 systemd-logind 1807 firefox 1866 Privileged Cont 1886 firefox 1887 firefox 1918 WebExtensions 1962 Web Content 1990 Web Content 2036 systemd 2065 dbus-daemon 2071 Xorg 2078 Xorg 2204 dbus-daemon 2839 Web Content 3372 skypeforlinux 3375 skypeforlinux 3502 skypeforlinux 3523 skypeforlinux 3526 skypeforlinux 3528 skypeforlinux 3550 skypeforlinux 3556 skypeforlinux 3558 skypeforlinux 3560 skypeforlinux 3562 skypeforlinux 3578 skypeforlinux 3586 skypeforlinux 3610 skypeforlinux 7883 cupsd 11819 Web Content 11998 Web Content 12091 Web Content 12207 Web Content 12284 Web Content [<0>] ep_poll+0x3d0/0x420 [<0>] do_epoll_wait+0xb8/0xd0 [<0>] __x64_sys_epoll_wait+0x1e/0x30 [<0>] do_syscall_64+0x5a/0x130 [<0>] entry_SYSCALL_64_after_hwframe+0x44/0xa9 2 kthreadd [<0>] kthreadd+0x2cb/0x2e0 [<0>] ret_from_fork+0x35/0x40 ... |
