Hello, Even though this is not a systemd problem, I believe systemd mailing list is a good place to discuss.
Our kernel has CONFIG_MEMCG enabled. As soon as we set DefaultMemoryAccounting=yes, our system wide memory usage increased 11 MB. The increase is mostly on kmalloc-* slab memory with the peak on kmalloc-32. I initially thought the increase is due to systemd creating system.slice under /sys/fs/cgroup/memory but I think I am wrong. I have run "systemd-run -p MemoryLimit=10M /bin/sleep 5" command while DefaultMemoryAccounting=no and there was no significant memory usage. I am quite puzzled about where this extra cost is coming from. Does anybody have any idea?
