The vmstat file there sounds normal... Can you run xymonlaunch with
--debug and see what it's reporting back? Also, strace what it's doing
when the next expected run occurs?

For testing purposes you can bring the interval down to 30s or so. The
only change you should notice is having multiple backgrounded vmstat
processes going at once in a round-robin fashion.
