Could you advice any best practise configs that I could use in my ELK setup for APM server to avoid error below on otel-collectors? (I added more resource on ELK to fix this error for the first time, but we faced it again on some collectos)

"The error is not retryable. Dropping data. {"kind": "exporter", "data\_type": "traces", "name": "otlp", "error": "Permanent error: rpc error: code = Unknown desc = sending queue is full", "dropped\_items": 1}"
