dominikriemer opened a new issue, #566:
URL: https://github.com/apache/streampipes/issues/566

   Hi,
   
   we are using streampipes in kubernetes where we have a mqtt broker in the same namespace which is used in a pipeline together with a mysql sink.
   
   The pipeline works and data is written into the database but in the morning around the same time there is no data written anymore into the database. If the pipeline is manually restarted it works again. I looked in the logs of the connect worker pod and I can see these kind of entries around the time when the pipeline stops.

   I also looked in the logs of the kafka container but there are no entries at this time.
   
   Do you know what could be the reason for this or how I can further debug it?
