Issue/Introduction

The following log messages may be seen within the gateways ssg_0_0.log file:

 

com.l7tech.server.service.ServiceMetricsServicesImpl: Failed to save a MetricsBin due to constraint violation 

org.hibernate.util.JDBCExceptionReporter: SQL Error: 1062, SQLState: 23000

org.hibernate.util.JDBCExceptionReporter: Duplicate entry 'xxxxxxxxxxxxxxx' for key 'nodeid' 

Cause

There is a known defect in the 8.x release of the gateway where restarting the gateway by executing:

 

service ssg restart

 

might not bring down the gateway processes gracefully resulting in multiple gateway processes

running which lead to the messages in question being seen.

 

 

Environment

This situation has been seen on the 8.x and 9.x release of the gateway

Resolution

This can be resolved in the interim by performing the following procedure: 

1. Stop the Gateway service: service ssg stop 

2. Kill all remaining Gateway processes: ps awwx | grep [G]ateway.jar | awk $'{print $1}' | xargs kill -9 

3. Start the Gateway service: service ssg start

 

We would suggest to stop the gateway going forward by executing:

 

service ssg stop

 

We would suggest to start the gateway going forward by executing:

 

service ssg start
