Hey David,
Can you check the cpu usage in the sar on the rest of the cluster (going backwards from the day you found the high cpu usage), so we can know if this behaviour was obseerved on other nodes.
Maybe that behaviour was "normal" for the push node (which could be another one) .
As this script is python, I guess you can put some debug print statements in it.
Best Regards,
Strahil Nikolov
