Hello,
Although the post is not fresh, but that behavior is still here in almost 2019.
We use a domestic Windows application using a MySQL 6.8.3 .Net connector to work with a 5.7.19 MySQL DB at a centos host.
And occasionally, and different hours of a day, and not every day, we get similar messages.
What is the proper way to resolve/avoid/workaround that problem ?
Best regards and looking forward the community assistance,
Avi Vainshtien
