[Xymon] Linux load question

I have a linux server which is alerting on a high load but the load average is lower than my threshold.  My question, why is it going red?

Analysis.cfg
HOST=serverA
        LOAD    89.0 90.0

Here are the top results - I expect that the alert should be triggered by the load average of 21.75 which is far lower than the thresholds.
top - 07:58:55 up 17 days, 19:31, 20 users,  load average: 21.75, 25.16, 25.32
...

But, there is a single process using a ton of cpu on one of the multiple cores - is this factoring into the alert?  If so, why is it not documented?
   PID USER      PR  NI    VIRT    RES    SHR S  %CPU %MEM     TIME+ COMMAND
121978 user1+    20   0 46.839g 0.040t  50388 S  2774 17.2  18504:34 python

Thanks,
John
