WARNING] --- Your harvester appears to be offline! No events for the past 901 seconds. (keep_alive_monitor.py:83)

I get this error every 5 minutes, even if the harvester is up and running. Sometimes it helps to kill the chiadog process, rm debug.log.offset and restart everything.

Environment:

• OS: Linux uranian 5.10.39-v8+ #1421 SMP PREEMPT Tue May 25 11:04:26 BST 2021 aarch64 GNU/Linux
• Python version: Python 3.7.3
• PIP version: pip 18.1 from /usr/lib/python3/dist-packages/pip (python 3.7)
• Chia version: 1.1.7

I had the same problem after sudden PC reboot, an garbage has been written into logs and log consumer has been confused and throwing exception at start:

Exception in thread Thread-1:

It looks like the consumer thread is crashed, so for chiadog it looks like there is no changes in the chia logs, so offline state assumed?

It looks like the consumer thread is crashed, so for chiadog it looks like there is no changes in the chia logs, so offline state assumed?

This is a known bug for which a fix is in the pipeline.
Meanwhile, deleting the debug.log.offset file from the Chiadog directory will fix this issue.
