in a 10.8.1 environment we currently have a strange behavior. Very often the GeoEvent Server is not responding anymore and the REST interface will be unavailable etc.
In the kafka log we still get the following error message all few seconds:
ERROR | pool-16-thread-1 | ConsumerCoordinator | 60 - com.esri.ges.framework.messaging.jms-messaging - 10.8.1 | [Consumer clientId=consumer-2, groupId=****] Offset commit failed on partition *** at offset xxxx: The coordinator is not aware of this member.
What is the best solution to solve this problem? For the moment we tested stuff like restart, clear data folder, redeploy custom components etc.
