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.
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:

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.
