I have a PC running windows 7 and MySQL 5.6. Data is uploaded to the server via java. They work nicely without any error. I just migrate to windows 10 and MySQL 5.7. The same program is used to upload data without any error in the java side. I also check that the data are written into the database. However, i got lots of [note] in the error log
Aborted connection 48 to db: 'XXX' user: 'root' host: 'localhost' (Got an error reading communication packets)
I have try following (MySQL Error Reading Communication Packets) and same result occurred. Whats wrong ?
