From: David Ahern <dsahern@gmail.com>
Following a prelink run mapped files for long running processes can show as deleted. The current message suggests restarting long running processes. Add to that a suggestion that prelink might be the cause.
Old message: /lib64/libc-2.14.so was updated, restart the long running apps that use it!
New message: /lib64/libc-2.14.so was updated (is prelink enabled?). Restart the long running apps that use it!
