**Problem** The first step in flushing mutations from the Batch Writer to the Tablet Servers involves binning mutations by destination tablet server. If the tablet server throws an OutOfMemoryError or any non-Exception based Throwable, the error will be thrown on the client side. The error will not be caught and will cause the bin thread to die without reporting the fact that an error occurred. This is unrecoverable and leaves the batch writer stuck waiting for mutations get flushed that never will. **Affected versions** 1.10.x, main **To Reproduce** Not easily reproducible. One could write a rogue iterator that throws an OutOfMemoryError when the metadata table is being scanned. **Bug Location** https://github.com/apache/accumulo/blob/5f20e38628abd6385a5ee652634f4d748ecd013f/core/src/main/java/org/apache/accumulo/core/clientImpl/TabletServerBatchWriter.java#L706 this: `catch (Exception e) {` should be changed to: `catch (Throwable e) {` -- This is an automated message from the Apache Git Service.
