I have 7 clients running. Each client has a different name. They are all
sending data to the primary Xymon server. The alerts are reading missing
processes, full file systems, and msgs errors. Here is another sample of an
unusual error. You can see the process list has a funky break in it.

 Sun Jan 17 15:40:18 MST 2010 - Processes NOT ok
