All right,
After reading a few discussions on these forums, I think I'm getting a partial hang of it...but I still want some clarification.
free -m, when --meminfo privvmpages:1 is set returns the "physpages", right? So why is there such a gap between my physpages and whats actually being used in privvmpages?
vzmemcheck -vA returns this:
Output values in Mbytes
veid LowMem LowMem RAM MemSwap MemSwap Alloc Alloc Alloc
util commit util util commit util commit limit
1 6.15 13.61 90.50 90.50 37.61 250.94 1037.61 1037.61
-------------------------------------------------------------------------
Summary: 6.15 13.61 90.50 90.50 37.61 250.94 1037.61 1037.61
1579.00 1579.00 3949.00 10093.00 10093.00 10093.00 10093.00 10093.00
I realize the kernel memory isn't included, but free -m returns 84MB being used and in privvmpages, it says I'm using ~250MB.
Also where does SWAP come into play? I have 4GB of RAM and 6GB swap partition but it seems that the SWAP is never used even when a VPS is maxed out on RAM usage. I started getting fork errors but I still had 0/6GB Swap usage.
Is there a setting I should set for how much SWAP a VPS can use? Or do I set privvmpages for SWAP + RAM and then maybe vmguarpages for just RAM?
Any help would be greatly appreciated!
Thanks,
Devon
[EDIT]
Maybe someone can give me some exact values...
I want a VPS with 1024MB RAM and 1024MB SWAP available, right now I have privvmpages and vmguarpages to 262144.
