This article applies to MetaDefender Secure Storage version older than 4.1.0 deployed on Windows and Linux systems.
Issue:
The Discovery Service becomes unresponsive or stops working. Log entries show timeout and retry messages in the PublishHandler, along with RabbitMQ connection errors such as:
xxxxxxxxxx2
1
Already closed: The AMQP operation was interrupted2
Close reason: code=406Possible Causes:
- Missing or misconfigured target exchange in RabbitMQ.
- Transient network interruptions or broker restarts leading to dropped connections.
- RabbitMQ reaching connection or channel limits, causing timeouts.
Resolution:
Upgrade the Helm chart to use MDSS version 4.1.0. This version includes fixes for Discovery Service stability and RabbitMQ connection handling.
