Strange error: Invalid non-numeric rollup type: AVERAGE

[v8dave]

I am seeing this error in the log file and not sure whats causing this.

WARN  2016-08-03 14:34:22,050 (com.serotonin.m2m2.web.mvc.rest.v1.model.pointValue.PointValueRollupCalculator.streamData:108) - Invalid non-numeric rollup type: AVERAGE 

Then this appears after it.

ERROR 2016-08-03 13:08:21,169 (com.serotonin.m2m2.web.mvc.rest.v1.publisher.pointValue.PointValueWebSocketPublisher.pointUpdated:156) - Websocket session is closed, can't send message

After these appear a few times, Mango shutsdown and my cron job restarts it.

Hi Dave,

Neither of those messages suggest a stability issue. In the first message, the rollup type of "AVERAGE" seems like it is being applied to a boolean or alphanumeric point. The code just defaults this to a rollup of "FIRST" and logs the warning.

The second, the exception for a closed session, is logged and that should be the end of it.

What's the behavior of the shutdown?

I don't have any boolean points showing on any dashboard displays.
