To resolve this issue you must increase the value of the MySQL variable: max_allowed_packet
The value will be different for each environment and the sample below is only provided as a guideline. Please refer to your DBA or MySQL documentation for further guidance in refining this to best suit your environment.
This command can be run at the MySQL prompt to dynamically change the value. Please note this will affect all new connections until a restart occurs.
SET GLOBAL max_allowed_packet = 33554432;
