The producer and consumer startup failed and the group IDs are duplicates

Last Updated: Mar 28, 2019

Possible causes

Multiple producer or consumer instances are started in the same JVM process, and these instances are configured with the same group ID, resulting in client startup failure.

Recommended solution

Perform the following steps:

  1. Make sure that only one producer or consumer instance under the same group ID is started in a JVM process. In other words, one producer instance and one consumer instance under the same group ID can be started simultaneously in a JVM process, but multiple producer or consumer instances are not allowed to be started simultaneously.

  2. Restart the application.
