Re: MySQL 5.7 Help!!

Is the last para at https://dev.mysql.com/doc/refman/5.7/en/packet-too-large.html relevant ...

You can also get strange problems with large packets if you are using large BLOB values but have not given mysqld access to enough memory to handle the query. If you suspect this is the case, try adding ulimit -d 256000 to the beginning of the mysqld_safe script and restarting mysqld.

If not, let's see the Show Create table stmt for the table on which the error is occurring, the dump stmt that is eliciting the error, and the exact error message.
