Description Minh, Hoang Ng. 1999-11-20 06:21:01 UTC

I'm running RedHat 6.0 kernel 2.2.5-15 SMP on a single PIII 500 Dell
server (this server support multi processor). System use to work well
until in last few days I could not run passwd at all. It will be back to
work if I restart the server but then the problem come back. Think of
maybe something is wrong with passwd package ship with RedHat 6, I updated
the package came with RedHat 6.1 but have the same result. Below is a
sample for what I have in messages file:

This looks a lot like a hardware problem that you're having - and some memory
corruption that happens as a result and is by chance experienced when running
the passwd binary

If the kernel continues to Oops on you please try the development kernels from
rawhide.
