Hi Dennis, Keith,
Thanks for your pointers.
I tried disabling C-states and and pcie-aspm options. No luck so far. My
box has to be rebooted
once in every 2-3 days.
Following is the last info in my syslog before reboot.

Hi,
My linux machine hangs after some period of inactivity (8+ hrs).
Anyone experiencing similar issue.
CentOS
Release 6.5(Final)
Kernel Linux 2.6.32-431.el6_x86_64
GNOME 2.28.2
Processor (0 - 7):
Intel(R) Core(TM) i7-4770 CPU @ 3.40 GHz
Any pointers will be helpful.
Thanks,
--Arvind

The canonical first place to check is your logs, many of which are in
/var/log/ . Beyond that, information about running apps at the time you
leave it before it crashes would be helpful, and you might try not
logging in to see if the problem occurs with no user activity (if not,
it points to an app that starts when you log in).

You can try running the machine with the kernel option "pcie_aspm=off"
and see if that helps and also try to disable C-States or Power Saving
all together in the BIOS.
More Details here:
https://access.redhat.com/site/documentation/en-US/Red_Hat_Enterprise_Linux/6/html/Power_Management_Guide/ASPM.html
http://lists.us.dell.com/pipermail/linux-poweredge/2011-June/044901.html
I've experienced lock-ups in the past because of these issues. The
network device hung because it tried to go into power saving mode using
ASPM and it failed and whole servers locked-up after being idle for a
while because of a bug in Intel Processors regarding the deeper power
saving modes (C-States) although these are supposed to be fixed since
6.3. Hope this helps.
Regards,
Dennis
