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

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.

  • hi rob,

    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.

  • hi mark,

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