hi all,
can someone help explaining what we are seeing? it makes no sense to us. this is a host running centos 7.4 with 3.10.0-693.17.1 kernel, and it has 192GB of ram
[] free -b total used free shared buff/cache available Mem: 201402642432 14413479936 75642777600 48586752 111346384896 185689632768 Swap: 21474832384 31961088 21442871296 [] cat /sys/fs/cgroup/memory/memory.max_usage_in_bytes 273102151680
how can the max be so much higher than total, and this is not even memsw?
either we're very tired and are overlooking something obvious, or there's something new to be learned ;)
many thanks,
stijn

Wonder if it's overcommitting memory.VMs do that, as a matter of course.

should have mentioned this, but this is not a VM. also, i expect any overcommit related numbers to show up in the memsw counters

Binary K,M,G are 1024 multiples not 1000 so total seems a little low.

no, it's a bit lower than i expected, but it's the ususal reserved/absent memory (dmesg|grep Memory)
and i mainly want to know why the max is higher than the limit.
