I have a python(fabric) script running on a centos 6 box that parses configuration files and daemonizes MRTG process and dumps rrd files a folder in a shared file system. All goes well but midway to the process I get the error [image attached below].

Command issued , fab -f /path/to/my/fabfile.py $functionName

It parses around 260 configuration files and dumps the rrds for the same. I am out of ideas as what might have caused this and am still searching for solutions. I disabled ksm/ksmtuned (just a hit) but that did not solve it.

Error

UPDATE

I installed same OS with same kernel, same scripts and same python version, everything identical ... on a different server, which is comparatively newer than the one earlier, and so far haven't experienced any issues, its been a couple of hours now. So it puts out the server/software being a reason for the error so far, probably its the hardware!! Will try upgrading the BIOS on the older one as a few links online suggested having similar issues with older version of BIOS when running disk-intensive processes. Would update my findings.

It seems one of the memory module installed was the issue. Changing it seems to have solved the problem.

In future when you have weird core dumps or GPF's , always take the server down and run a memtest from the grub menu.
