I had this issue not long ago and it turned out to be a hardware issue. The memory was bad. I was able to recreate this by running some command like: find / -name file_that_doesnt_exist -print (just so that it will go thru the whole FS). It would puke almost instantly. We replaced the memory and it never happened again. hope this helps -pranav ******************************************************************* Pranav A.
