Being not able to kill a server running in an endless loop seems strange to me. If you put any program artificially into an endless loop, you can kill it via "kill -9 <pid>". Have you tried that? The only exception I 
can imagine is if there is a problem in the file system, like your elog logbooks are mounted via NFS or some other remote filesystem, and you have a problem there. Since the process might be stuck in kernel 
mode, you cannot kill it. That's why I have all my servers running on local file systems. Just another thought.
