Hello all,
One of my linux servers crash with a 'kernal panic: VFS: LRU block list
corrupted' message on my screen.
I reboot with a boot disk - it was find, then rebooted of the hard drive
and it was fine. The systems is runing fine
now, but i thought maybe someone on this list could explain to me what
exactly happend there.
My /var/log/messages files displays this:

My boss and I looked over it and it looks like something to do with virtual
memory.
I was logged in remotely ussing SSH and was using LAME to convert some
wav's to mp3's
my boss suggested that one of the wav files might have been corrupted.
What can you guys suggest?
