Package: lxcfs Version: 4.0.7-1 Severity: important Dear Maintainer,
On a large server, lxcfs takes 2 or 3 CPU cores constantly (and running ps -ax inside a container is slow) * What led up to the situation? There are more than 250 containers running. There are 6,000 processes spread out in all those containers with 60,000 threads running. * What exactly did you do (or not do) that was effective (or ineffective)? If you have less processes/containers, then there is no problem with CPU. Problem appears to get worse as the number of containers/processes increases. It can take more than 20 seconds for 'ps -ax' running within a container to return anything, even in small containers where the list of processes returned is very small (less than 50). -- System Information: Debian Release: 11.2 APT prefers stable-updates APT policy: (500, 'stable-updates'), (500, 'stable-security'), (500, 'stable'), (90, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 5.10.0-10-amd64 (SMP w/96 CPU threads) Kernel taint flags: TAINT_PROPRIETARY_MODULE, TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE not set Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages lxcfs depends on: ii init-system-helpers 1.60 ii libc6 2.31-13+deb11u2 ii libfuse2 2.9.9-5 ii libgcc-s1 10.2.1-6 ii lsb-base 11.1.0 lxcfs recommends no packages. lxcfs suggests no packages. -- no debconf information
