Known issues

  • Authentication - Application-type users connect with Memphis (via the SDKs) using a connection token. For now, this token is constant and randomly generated per Memphis deployment.
  • While using an older SDK version, an error message appears on the station overview page saying, “Error while getting notified about a poison message: Missing mandatory message headers.”
  • When storage capacity reaches 100%, Memphis GUI becomes unresponsive till cleaned up by at least 10%.
  • Resending/dropping a great amount of dead-letter messages can significantly take time.
