Hi,

since a few days I have a strange problem. My homeduino devices stop working and if I look into the daemon log, there are just thousands of lines with comma separated numbers with an ACK at the end. It looks like raw data (an example later), but my log files get overloaded with the numbers. In all log files, .log, .log.0, .log.1 and .log.2 there are just numbers, so I cannot see, when this trouble started.

Here is an example (but just the end, there are more than 30000 lines):

I am using pimatic 0.9.42 on a raspberry 3 with an Arduino Uno.
Never had that problem until now.

So I have some questions:

Does someone know from my description what could be wrong?

Where can I configure the size of the log files that they use more than 1 MB before rotating and overwrite the old log files?

Is there a way to configure to keep more than 3 (.0, .1, .2) old log files before log rotation happens?

Thank you in advance,
Martin
