"No response from slave ..." errors before MySQL backup starts
-
Hi All,
We are getting a modbus "No response from slave ..." errors from most of our Modbus slaves average 4-5 minutes before every MySQL backup start.
What happens in our system in order of time are as follows.
We configured to backup MySQL everyday at 19.10 PM.
"No response from slave ..." errors start everyday around 19.05~ and ends around 19:12 PM
The backup file is created within an average of 6 minutes every day after the backup starts. That means, backup is finished around at 19:16 PM.Is there any pre-tasks of MySQL backup that would trigger modbus errors?
Any idea what could be the reason?Thanks in advance!

Check used threads and pending work items...
There appears to be a trend at the moment of items hanging or crashing due to insufficient worker threads available.Fox
