### Search before asking - [x] I searched in the [issues](https://github.com/apache/fluss/issues) and found nothing similar. ### Fluss version 0.9.0 (latest release) ### Please describe the bug 🐞 The Fluss write sender I/O thread crashes with `java.lang.IllegalArgumentException: Accounted size went negative`, originating from Apache Arrow's internal memory accounting layer. The error surfaces during server upgrade (though the exact correlation is unclear). **Full Stack Trace:** ``` 2026-03-16 18:26:55,245 [fluss-write-sender-thread-1] ERROR org.apache.fluss.client.write.Sender [] - Uncaught error in Fluss write sender I/O thread: java.lang.IllegalArgumentException: Accounted size went negative. at org.apache.fluss.shaded.arrow.org.apache.arrow.util.Preconditions.checkArgument(Preconditions.java:136) at org.apache.fluss.shaded.arrow.org.apache.arrow.memory.Accountant.releaseBytes(Accountant.java:219) at org.apache.fluss.shaded.arrow.org.apache.arrow.memory.RootAllocator.releaseBytes(RootAllocator.java:29) at org.apache.fluss.shaded.arrow.org.apache.arrow.memory.AllocationManager.release(AllocationManager.java:152) at org.apache.fluss.shaded.arrow.org.apache.arrow.memory.BufferLedger.decrement(BufferLedger.java:157) at org.apache.fluss.shaded.arrow.org.apache.arrow.memory.BufferLedger.release(BufferLedger.java:124) at org.apache.fluss.shaded.arrow.org.apache.arrow.memory.BufferLedger.release(BufferLedger.java:104) at org.apache.fluss.shaded.arrow.org.apache.arrow.vector.ipc.message.ArrowRecordBatch.close(ArrowRecordBatch.java:243) at org.apache.fluss.row.arrow.ArrowWriter.serializeToOutputView(ArrowWriter.java:266) at org.apache.fluss.record.MemoryLogRecordsArrowBuilder.build(MemoryLogRecordsArrowBuilder.java:145) at org.apache.fluss.record.MemoryLogRecordsArrowBuilder.close(MemoryLogRecordsArrowBuilder.java:228) at org.apache.fluss.client.write.ArrowLogWriteBatch.close(ArrowLogWriteBatch.java:100) at org.apache.fluss.client.write.RecordAccumulator.drainBatchesForOneNode(RecordAccumulator.java:731) at org.apache.fluss.client.write.RecordAccumulator.drain(RecordAccumulator.java:286) at org.apache.fluss.client.write.Sender.sendWriteData(Sender.java:243) at org.apache.fluss.client.write.Sender.runOnce(Sender.java:194) at org.apache.fluss.client.write.Sender.run(Sender.java:164) ``` ### Solution _No response_ ### Are you willing to submit a PR? - [ ] I'm willing to submit a PR! -- This is an automated message from the Apache Git Service.
