Hi,  
We're seeing this warning in our logstash logs:

```auto
[2025-03-10T09:26:40,147][WARN][org.logstash.beats.V2Batch][base-input][beats-input] Received batch of size 67137414 bytes that is too large to fit into the pre-allocated memory pool. This will cause a performance degradation. Set 'io.netty.allocator.maxOrder' JVM property to 14 to accommodate batches bigger than 67108864 bytes.

```

We're already running with a maxOrder value of 13. How should we be reacting to this warning?

Thx
