| |
Hi,
I'm hoping you can help me out. I'm on a 2.6.27 x86 system and I'm seeing the "inactive" field in /proc/meminfo slowly growing over time to the point where eventually the oom-killer kicks in and starts killing things. The growth is not evident in any other field in /proc/meminfo.
I'm trying to figure out where the memory is going, and what it's being used for.
As I've found, the fields in /proc/meminfo don't add up...in particular, active+inactive is quite a bit larger than buffers+cached+dirty+anonpages+mapped+pagetables+vmallocused. Initially the difference is about 156MB, but after about 13 hrs the difference is 240MB.
How can I track down where this is going? Can you suggest any instrumentation that I can add?
I'm reasonably capable, but I'm getting seriously confused trying to sort out the memory subsystem. Some pointers would be appreciated.
Thanks,
Chris
