I've got both a dual-core i686 notebook and a dual-core x86_64 desktop, and
I've /never/ seen anything like this... The following are the things I
check first when seeing aberrant behaviour:

Have you checked the hardware (memtest, overheating due to bad fan, ...)?

Bad electric power (yes, some machines here used to go crazy due to voltage
fluctuations)? Bad/undersized power supply?

Have you checked the relevant packages (at least yum, rpm, glibc,
fileutils, etc; "rpm -q --requires ..." should point you in the right
direction)? "rpm -V ..." is your friend.

/var (or other filesystems) filled up? (Yes, rpm (at least used to) go nuts
and spew strange messages)

Anybody frobbing disk parameters "for performance"?! That leads to
(regrettably mostly silent) filesystem corruption... Overclocking?
