Errors filling up log with Aeon Labs 4-in-1 multi sensor

Good afternoon all,

Having an issue with my 4-in-1 sensors filling up the log file. Not sure where this is coming from or how to resolve. These messages come up about every second for about 10-15 minutes every few days.

Have already removed/readded, changed batteries, etc.

I will paste only one message here as the log file is about 10MB in size with all of them... Apologies in advance as this is very hard to read...

[EDIT]
Well, the paste didn't work - exceeded post size limit. Here is the beginning and the tail end...
