Is your root FS mounted read-only? I'm not sure if this can happen, but it
could be that the cached version of these files (which reside in RAM) could
have got corrupted? I haven't played around with JFFS2 much (mostly used
YAFFS2) so maybe somebody experienced with JFFS2 can throw some light on
this.

Can you reformat your flash and put the root FS again on it? While
formatting see if bad blocks are reported.
