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

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?
Binary K,M,G are 1024 multiples not 1000 so total seems a little low.
either we're very tired and are overlooking something obvious, or
there's something new to be learned ;)

many thanks,

stijn
