Bug Description
Same as #1655842 - Started seeing oom-killer on multiple servers upgraded to 4.4.0-59.
Unlike #1655842, also seeing the same oom-killer on multiple servers updated to 4.8.0-34.
First upgraded them all 4.8 servers 4.8.0-36, then downgraded a few to 4.4.0-63. I am seeing an even more pronounced change in the memory usage, so I can only assume that 4.4.0-63 is also bugged with the same problem as 4.4.0-59 and 4.8.0-34. Either because #1655842 is not fixed, or it is only fixed for certain kinds of workloads.
These are the changes I'm seeing in our memory graphs between 4.4.0-59 and 4.4.0-63/4.8.0-34.
The symptoms I'm seeing are:
Upgrading 4.4.0-57 -> 4.4.0-59:
- /proc/meminfo:
- /proc/meminfo:
- /proc/meminfo:
- /proc/meminfo:
Upgrading 4.4.0-57 -> 4.4.0-63:
- /proc/meminfo:
- /proc/meminfo:
- /proc/meminfo:
- /proc/meminfo:
Upgrading 4.4.0-57 -> 4.8.0-34:
- /proc/meminfo:
- /proc/meminfo:
- /proc/meminfo:
- /proc/meminfo:
Setting vm.vfs_
Downgrading to 4.4.0-57 also works.
Will also note that I haven't had a definitive OOM in 4.4.0-63. But the shift in memory usage is far too much from what I expect to be normal on these particular servers where I'm experiencing crashes.
