The ssg logs are showing the following JDBC Exception on the CA API Gateway:

com.l7tech.server.policy.assertion.ServerAuditDetailAssertion: -4: Policy Fragment: LogSink 

com.l7tech.server.message: Message processed successfully 

org.hibernate.util.JDBCExceptionReporter: SQL Error: 0, SQLState: S1000 

org.hibernate.util.JDBCExceptionReporter: Packet for query is too large (58888888 > 33554432). You can change this value on the server by setting the max_allowed_packet' variable. 


The 'Packet for query is too large' message would indicate that the size of the payload is responsible for the situation.

There is a maximum packet size of 32MB allowed in audit details.


This can be rectified globally by adjusting the setting in the following file: 

/etc/my.cnf - change max_allowed_packet to a value larger than 32MB.


In order to activate the change on the Gateway, it is required to stop ssg, restart mysql and thereafter start ssg.
