Environment

Release : 10.7.0

Component : APM Agents

Resolution

These error messages are coming from the MQ. They do not have any impact on the APM or MQ side. The agent handles the bad exceptions and tries to reconnect after 5 minutes wait. Since developers already anticipated these exceptions, the ones listed in the logs can happen without any major issues at the MQ server end. The connection will be retried after 5 minutes. As a result, these error messages are temporary.
