MySQL server has gone away
or
MySQL: got a packet bigger than ‘max_allowed_packet’ bytes

Fix:
You need to increase mysql variables  max_allowed_packet and global net_buffer_length in mysql database


Login is root and set this.

mysql> set global max_allowed_packet=2000000000;
mysql> set global net_buffer_length=2000000;
