ERROR 2006 mysql

Question

I'm trying to make an attachment of a very large value, this value has 2530000 characters. But I'm throwing an error:

ERROR 2006 (HY000) at line 867015: MySQL server has gone away

I tried :

max_allowed_packet=3562M

sql_mode = ""

innodb_buffer_pool_size = 256M

innodb_additional_mem_pool_size = 10M

 innodb_lock_wait_timeout = 180

Answer 1

Maybe:

wait_timeout=28800 interactive_timeout = 28800 max_allowed_packet=16M
