alluxuio worker exits unexpectedly

[coderwf]

Alluxio Version:
2.9.6

The Alluxio worker exits, but no dump file is found despite the DumpOnOOM configuration being set. According to machine monitoring, both memory usage and CPU utilization are below 60%. Additionally, the system's Killer logs have been checked, and no similar logs were found. So what exactly is the cause of this issue? No abnormalities were found in the worker's worker.out and worker.log files. The last few lines in worker.out show: "WARN alluxio-process-shutdown-hook - Alluxio worker gRPC server shutdown timed out.", but the specific reason remains unknown.

Maybe I can provide more log information, but I'm not sure which ones.

Can you share the worker and master log? Maybe some issue is ignored.
