+::::{dropdown} Details
+
+Attempts to start Logstash when `queue.max_bytes` has been set to `2147483648` bytes or greater will fail. There is currently no workaround for this issue other than downgrading to a previous version of Logstash. Therefore we recommend that any Logstash users with a Persistent Queue greater than size not upgrade to Logstash `9.2.0`.

+Details of the bug are included in [this PR fixing the issue](https://github.com/elastic/logstash/pull/18366), which will be included in a future version of Logstash.
