any ideas?

That’s an Ä

That’s a °

Maybe you have devices that are sending those ascii chars?

3

could be that there are such devices - sending such characters … but they should not crash the mkeventd … I need to restart the mkeventd … only after the restart the processing works again …
that the behavior that I have seen so far … maybe there is also another reason for this (file limits etc. … that’s what I already checked)

any solution ideas how to prevent such an error or how to find more about the problem are welcome …
