2-5 - Filtering Provider Failure

Possible Causes

• Dubbo selects a provider from the list of providers to make a call during load balancing. If the provider list changes during the selection process, read/write conflicts may occur, leading to filtering exceptions.
• When the Dubbo retry mechanism encounters a failure in calling the provider, it will re-filter another provider for the call, and exceptions may occur during the re-filtering process.

Troubleshooting and Resolution Steps

1. Check the list of providers in the registry and the availability of the corresponding providers.
2. Raise an issue in the community, providing on-site environment information and reproduction steps.
