No such issues with at least 2.6.15-1.1831 kernel.
But some time back there was similar problem. It turned out to be some corrupt files.
Checked for out of the way Over-sized directories. Then proceeded down the sub-directories.
If it can be deleted I did, else I updated the concerned the rpm.
It is mostly corrupt files. If U suspect bad memory module - run the memtest from rescue disc.
