I'm trying to work out why my database dump won't import on my new server. I'm using:

mysql --max_allowed_packet=512M -uDB_USERNAME -pPASS DB_NAME < /root/backup.sql

After a while of it running, I then get in /var/log/mysql/error.log:

2017-09-19T15:00:06.077222Z 130 [Note] Aborted connection 130 to db: 'DB_NAME' user: 'DB_USER' host: 'localhost' (Got a packet bigger than 'max_allowed_packet' bytes)

and the "mysql" CLI call comes back with:

ERROR 2006 (HY000) at line 5995: MySQL server has gone away

Here is some of the other mySQL config:

key_buffer_size     = 16M
max_allowed_packet  = 512M
thread_stack        = 192K
thread_cache_size       = 8
# This replaces the startup script and checks MyISAM tables if needed
# the first time they are touched
myisam-recover-options  = BACKUP
#max_connections        = 100
#table_cache            = 64
#thread_concurrency     = 10
#

I'm at a bit of a loss as to what to try. Any suggestions? The SQL file is 7gb, and the table it keeps dying on is 5gb on the old server.

Thanks!

At input line 5995 of your input you should find a line longer than 512M. Adjust your max_allowed_packet to cover it * 1.25 for a little breathing space.
