Has anyone seen this issue? We're running containers under CentOS 7.2 and some
of these containers are reporting incorrect memory allocation in
/proc/meminfo. The output below comes from a system with 32G of memory and
84GB of swap. The values reported are completely wrong.
There was a meminfo bug here:
https://bugzilla.redhat.com/show_bug.cgi?id=1300781
The initial report is fixed in git, however the reporter also mentioned the
issue you are seeing. I suspect something is going wacky with the memory
values we are getting from host cgroups after some period of time. If you can
reproduce with Fedora (or RHEL) try filing a bug there

It's interesting that the value I see on my containers
(9007199254740991) is the exact same value that's reported in this Red
Hat bug. Clearly that is not a coincidence. We did not see this problem
in 7.1 so apparently it is something introduced in 7.2. For the
immediate term it looks like we'll have to roll back to 7.1.I'll look
into getting it reproduced in Federa or RHEL.
