Package: src:linux Version: 4.19.67-2+deb10u2 Severity: important Dear Maintainer, Since the latest Debian stable release, I observe a slab memory leak of about 30MB/hour when running the kernel 4.19.67-2+deb10u2 on an OVH VPS, which causes an all applications to slowly move to swap after a few days, and eventually an OOM. You'll find a typical munin memory plot attached to the bug report. This is the typical output off "slabtop -s c -o" at boot time: | Active / Total Objects (% used) : 174642 / 180042 (97,0%) | Active / Total Slabs (% used) : 6885 / 6885 (100,0%) | Active / Total

I have found that the problem has been introduced upstream in the 4.19.66 release. I have been able to bisect the issue on the upstream stable branch and found it has been introduced in that commit: | commit 4340d175b89896d069c1e875f5b98c80a408f680 | Author: Tejun Heo <tj@kernel.org> | Date: Fri May 31 10:38:58 2019 -0700 | | cgroup: Include dying leaders with live threads in PROCS iterations | | commit c03cd7738a83b13739f00546166969342c8ff014 upstream. | | CSS_TASK_ITER_PROCS currently iterates live group leaders; however, | this means that a process with dying leader and live threads will be | skipped. IOW, cgroup.procs might be empty while cgroup.threads isn't, | which is confusing to say the least. | | Fix it by making cset track dying tasks and include dying leaders with | live threads in PROCS iteration. | | Signed-off-by: Tejun Heo <tj@kernel.org> | Reported-and-tested-by: Topi Miettinen <toiwoton@gmail.com> | Cc: Oleg Nesterov <oleg@redhat.com> | Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> I am also able to reproduce the problem with the latest kernel from experimental, ie version 5.4-1~exp1. On the other hand I use the Debian stable kernel on many other machines, and they are not affected by the issue (but not of them are OVH VPS). -- Package-specific info: ** Kernel log: boot messages
