Are there known issues with embedded Kafka on Windows server for Pega v23?
We recently upgraded to Pega v23 in Windows OS (VM) but we have yet to externalize our Kafka. We have retained our embedded kafka services. However, we noticed that our Queue Processors sometimes stall or suddenly restart. One time 5 major QPs stopped clearing the Ready to Process queues (including pzStandardProcessor and pyProcessNotification) and we had to delete and recreate their instances.
We would like to seek more information on this. Is this a known issue and is there a solution (except externalizing Kafka)? Are there any other known issues?

@Jeremie There are known issues with Kafka getting restarted multiple times a day (reference 2) and Queue Processor errors like "Failed to prepare partitions" (reference 3). Solutions to these issues involve multiple configuration changes including JVM argument changes, DSS additions, ulimit updates for open files, and WebSphere Connection Pool Settings updates. However, these solutions are specific to the issues mentioned and may not solve your problem. It's recommended to raise a Pega Support Request for a more detailed investigation into your specific issue.
