I'm seeing a slow increase in memory consumption and I'm trying to narrow down the possible causes.
In my test, I got the system into steady-state and then started monitoring /proc/meminfo.
After 14 hrs: MemFree had dropped by 594MB. Active + Inactive + Slab increased by 594MB Buffers + Cached + AnonPages + Mapped + Slab increased by 290MB
The other categories in /proc/meminfo didn't change significantly.
I've done some experimenting and it seems that pages allocated in the kernel via alloc_page() and friends don't show up in /proc/meminfo except that they're deducted from the MemFree category. Specifically, they don't seem to show up in the Active/Inactive category. Can someone confirm this?
Given the above, what types of pages are in Active/Inactive other than Buffers + Cached + AnonPages + Mapped?
Thanks,
Chris
