Email seems to kill logger process

[jfmoore75]

Hi, I searched and found a similar issue from 2007 but that's so long ago I thought it was best to start a new thread. I added a few email notifications today and now the data logger no longer works. The log is full of messages saying that a child process received a termination signal. Test emails still work okay but event emails aren't sending. I suspect the problem is related to my Incremental alarms but haven't removed them yet to confirm that. My periodic email (email #1) was working until I added the alarm condition emails. Eventually the station hangs and I can no longer connect to it and have to reboot it and then everything repeats again.

[Edit]
After looking at this some more the problem seems to be related to having incremental alarms defined or having alarms triggered. When I just have the periodic email setup the data logger comes back up and all works fine

Here's what I see on the live data tab:
Data Logger Failure
Data logger does not provide data. Please check that station settings are correct.

Here's the log after a reboot:

Termination signal 8 is raised on floating point errors, like division by zero, etc.

Candidate in your definitions is a misuse of the modulus operator '%'.
To my knowledge this is defined for integers only.
([rain0total-daysum=in.2:0] + 0.05) % 0.1
