Download hangs during parallel transfer

[jjkoehorst]

I am using the jargon api to download some big files and most of the times this goes correct but sometimes it throws an unexpected length read when reading int error. This would normally not be such a big issue as I catch errors and try to download it again. However in this case it just hangs and I am not sure how to make sure that the jargon exception that is thrown is thrown through.

Any thoughts? Perhaps it could be in the call back listener or the transfer control block?

                StatusCallbackListener statusCallbackListener = new StatusCallbackListener();
                TransferControlBlock defaultTransferControlBlock = DefaultTransferControlBlock.instance();
                TransferOptions transferOptions = dataTransferOperationsAO.buildTransferOptionsBasedOnJargonProperties();
                transferOptions.setIntraFileStatusCallbacks(true);
                transferOptions.setIntraFileStatusCallbacksNumberCallsInterval(1);
                transferOptions.setIntraFileStatusCallbacksTotalBytesInterval(2);
                logger.debug("isComputeChecksumAfterTransfer " + transferOptions.isComputeChecksumAfterTransfer());
                logger.debug("isComputeAndVerifyChecksumAfterTransfer " + transferOptions.isComputeAndVerifyChecksumAfterTransfer());
                defaultTransferControlBlock.setTransferOptions(transferOptions);
                dataTransferOperationsAO.getOperation(irodsFile, localFile, statusCallbackListener, defaultTransferControlBlock);
