Hi everyone,
We’ve just released ServiceControl 4.12.1.
Fixed bugs
- #2148 Error/Audit ingestion stops when poison messages are received
- #2149 Duplicated error messages may lead to ServiceControl performance degradation
Error/Audit ingestion stops when poison messages are received
How to know if you are affected
You are affected if:
- You are running ServiceControl or ServiceControl Audit instances on version 4.5.0 or above
- There are messages in your error/audit queue that are missing NServiceBus headers - added by NServiceBus endpoints during normal processing. This problem happens mostly when integrating with non-NServiceBus endpoints.
Symptoms
When ServiceControl encounters messages in the error or audit queue that are missing a required header, the error/audit ingestion process stops and does not restart. ServiceControl stops processing messages from the error and audit queue and needs to be restarted.
Duplicated error messages may lead to ServiceControl performance degradation
How to know if you are affected
You are affected if some of the failed messages sent to the error queue are reprocessed by ServiceControl a significant number (100+) of times. This might be caused by physical duplicates reaching the error queue is most likely a symptom other problems that are present in the system.
Symptoms
You are affected if accessing failed message details - either via ServicePulse or API results in spiking CPU and memory (30 GB+) usage.
