reducing daily cronjob activities on h1hpipumpctrley has fixed pressure spike

yesterday I reduced the number of tasks crontab does daily at 04:02 on h1hpipumpctrley from eight to just one (log file rotation). Plot shows the PRESS1 signal, second trends, five minute duration 04:00 - 04:05 PDT. Left is Wed 3/22 (before change) right is this morning 3/23. As can be seen, glitch/spike has been fixed. I'll open a work permit to propagate this change to the other two units.
