Hi,

I am facing issue with nfs server which auto restart, some details as,

RHEL :- 6.5
kERNEL :- 2.6.32-431.el6.x86_64
Arch :- x86_64

Getting crash dump as,

<4>swapper: page allocation failure. order:1, mode:0x20

Kindly suggest if its a bug or other alternative can be done by tuning the kernel.

Also saw other similar post but they are still opened

Also, do we have any good document to analyse the crash dump ?
