[Kernel-packages] [Bug 1932586] Re: Processes launched during the NIC load is high may hang up.
The Hirsute Hippo has reached End of Life, so this bug will not be fixed for that release. ** Changed in: linux-raspi (Ubuntu Hirsute) Status: Confirmed => Won't Fix -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-raspi in Ubuntu. https://bugs.launchpad.net/bugs/1932586 Title: Processes launched during the NIC load is high may hang up. Status in linux-raspi package in Ubuntu: Confirmed Status in linux-raspi source package in Hirsute: Won't Fix Bug description: 1) The release of Ubuntu you are using, via 'lsb_release -rd' or System -> About Ubuntu ❯ lsb_release -rd Description:Ubuntu 21.04 Release:21.04 2) The version of the package you are using, via 'apt-cache policy pkgname' or by checking in Software Center ❯ LANG=C apt-cache policy linux-raspi linux-raspi: Installed: 5.11.0.1009.7 Candidate: 5.11.0.1009.7 Version table: *** 5.11.0.1009.7 500 500 http://ports.ubuntu.com/ubuntu-ports hirsute-updates/main arm64 Packages 500 http://ports.ubuntu.com/ubuntu-ports hirsute-security/main arm64 Packages 100 /var/lib/dpkg/status 5.11.0.1007.5 500 500 http://ports.ubuntu.com/ubuntu-ports hirsute/main arm64 Packages 3) What you expected to happen Processes launched during the NIC load is high will exit normally. 4) What happened instead I'm using hirsute on Raspberry Pi 4 model B(4GB RAM). Some processes launched during the NIC load is high might not exit. What "NIC load is high" means: - I have configured crontab to run Ookla's speedtest-cli which generates heavy network traffic every 15 minites. - During speedtest-cli, Softirq becomes higher. - SoC(BCM2711) built-in NIC(driver is bcmgenet) What "may not exit" means: - Some processes launched during speedtest-cli is running will not exit. It remains with consuming CPU 100% and not accept any signals including SIGKILL. - Those processes can't be attached by gdb or strace. Trying to do so, gdb and strace will freeze. I could't terminate the processes in any way. But the system could be rebooted by "sudo reboot" command. I configured RFS/RPS to distribute Softirq among CPU cores. It was quite effective, but did not prevent the problem completely.
