Hello list,
The "free" command gives me false number on vservers. Can someone reproduce
the same as below :
*) Host
linux 2.6.12.4, vs 2.0
server memory : 5 Go
*) On vserver #1 :
[EMAIL PROTECTED] # free
total used free
Mem: 5128164 1373868 3754296
-/+ buffers/cache: -3077072 8205236 <<<--- negative number
[EMAIL PROTECTED] # ps auxw | awk '{rss+=$6} END {print rss}'
1991724
*) On vserver #2 :
[EMAIL PROTECTED] # free -g
total used free
Mem: 4 0 4
-/+ buffers/cache: 4091 9 <<<--- 4To used !!
*) On the host :
[EMAIL PROTECTED] # free
total used free
Mem: 5128164 4964772 163392
-/+ buffers/cache: 512404 4615760
[EMAIL PROTECTED] # vps auxw | awk '$4 == "vs1" {rss+=$8} END {print rss}'
1989684
So with "ps" on the vserver or "vps" on the host, vserver #1 seems to consume
nearly 2Go of RSS. vserver-stat gives the same information.
But free gives a negative number for used memory on the vserver #1. And on
vserver #2, memory used is ... erk ... interesting.
Do you think this is related to vserver, perhaps because of a total memory
exceeding 4 Go (32 bits) ? Or is it a (known) limit of the "free" command ?
Thx
