Re: mysql V 8.0.12 and mysqdump

Hello list,
i run into an unexpected problem with mysqldump:

mysqldump --version
mysqldump  Ver 8.0.12 for Linux on x86_64 (MySQL Community Server - GPL)


when i try it results in:
mysqldump: Error: 'Lost connection to MySQL server during query' when trying to
dump tablespaces
mysqldump: Couldn't execute 'SHOW VARIABLES LIKE 'ndbinfo\_version'': MySQL
server has gone away (2006)

I regulary hav this problem with the command-line client (mysql.exe) and when I asked R H gave this answer (and with the command-line client it is much less imporant):
