Public bug reported:
I receive an intermittent error using iostat -k 5 : "Cannot open
/proc/stat: Cannot allocate memory"
This can also be simply reproduced by entering: "cat /proc/stat", one to
several (~5-10) times.
strace on the "cat /proc/stat" method:
...exclude typical run-up...
fstat(3, {st_mode=S_IFREG|0644, st_size=1607664, ...}) = 0

fstat(1, {st_mode=S_IFCHR|0620, st_rdev=makedev(136, 5), ...}) = 0

This only seems to happens on specific hardware: Intel Server System P4000CP / S2600CP Motherboard, booted with kernel option: "pci=conf1"
This does NOT happen on very similar hardware: Intel Server R2312GZ /
S2600GZ Motherboard
Is there a possible memory, or kernel memory sysctl configurable I'm missing here?
