I don't see a contact address, so I'll just send this to the list.
First, I would utilize rpm to verify that the binaries on the drive are what rpm
thinks it installed
a basic way (but will take some time) is:
rpm -Va
you could also just try:
rpm -Vf /bin/grep
if nothing is spit out, then it means the file matched what is expected, else it
will spit out a line like:
S.5....T c /etc/pam.d/system-auth
the order or those items is:
File Size
Mode
MD5 sum
major number/minor number
symlink string
owner
group
mod time
so, in my case, that file has a mismatch for Size (S), MD5 sum (5) and Mod time
(T). The little c tells me it is a config file.
You can also verify them agains rpm packages (in case you suspect corruption or
tampering of the rpm database itself) with the -p flag.
Hope this helps to begin to see what is up with your system. For me, the system
doesn't segfault so much as just have its load skyrocket and become unresponsive
when a system drive is dying.
