As far as I can determine wsprdaemon is running fine since I got it started a day or two ago. I have noticed that the log file is full of repeated error messages of this type:
Mon Oct 18 12:30:01 UTC 2021: watchdog_daemon() starting as pid 1112
sed: -e expression #1, char 16: unknown option to `s'
sed: -e expression #1, char 14: unknown option to `s'
sed: -e expression #1, char 16: unknown option to `s'
sed: -e expression #1, char 14: unknown option to `s'
sed: -e expression #1, char 16: unknown option to `s'...
The file size is about 159 kB right now after about 9 hours uptime, just wanted to make sure these are "benign" errors that won't eventually cause a problem.
