Ok, so I made the change and I do not get the error now. However, I still am getting text in the alarm.txt file that should not be there. I changed the evaluation for level > INFO to be level == ERROR. I am still getting info and debug messages in the alarm file. Also, SEND_ALARM has not been set in the code, yet I am getting log messages.
