Hi @sachinambardekar
Please check max_allowed_packets setting and tune it if requires higher value.
Check processlist if this is caused by timeout settings.

Thanks vaibhav_upadhyay40 . We are seeing below messages in error log file only after applying 5.7.30 patch. We never encounter this before.

I have seen tens of millions of those over the years Ive researched and looked and tried everything… Ive never been able to get rid of them as it is only a NOTE vs a warning or anything else I have just ignored them
