Soln :-

This error is occur due to due to expire of wait_timeout .

Just go to mysql server check its wait_timeout :

mysql> SHOW  VARIABLES  LIKE  'wait_timeout'

mysql> set global wait_timeout = 600 # 10 minute or maximum wait time out you need

Run these on MySQL DB

set global net_buffer_length=1000000; 
set global max_allowed_packet=1000000000;
