[Bug 1226172] Re: iostat: Cannot open /proc/stat: Cannot allocate memory
Additional memalloc failures gathered from syslog are attached. I have
limited this failure data, as there is 10MB of text crash info in the
syslog.
These failures are being caused by irqbalance, snmpd, vnstatd, etc.
Seemingly any application which relies upon /proc
I have included a similar crash from a 2nd system, identical hardware,
and same kernel.

Title:
iostat: Cannot open /proc/stat: Cannot allocate memory
Status in “linux” package in Ubuntu:
Confirmed
Bug description:
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:

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?
