+   when those queues were deleted.
+
+   GitHub issue: [#14138](https://github.com/rabbitmq/rabbitmq-server/pull/14138)
+
+ * Classic queues now retry opening files when flushing buffers to significantly reduce the probability of running into
+   `eacces` file system operation errors from the Windows kernel.
