             Summary: Handle payloads larger than 2k via SyslogUDPSource
                 Key: FLUME-2885
                 URL: https://issues.apache.org/jira/browse/FLUME-2885
             Project: Flume
          Issue Type: Bug
            Reporter: Javier León de Antonio


Syslog messages sent via UDP are truncated to 2k.

After a research, I found this issue : https://issues.apache.org/jira/browse/FLUME-2130

I saw you are using an AdaptiveReceiveBufferSizePredictorFactory to handle the buffer size from an initial size of 2k to a max size of 64k, but this BufferSizePredictor never grows. I searched a little more, and I found that AdaptiveReceiveBufferSizePredictorFactory only does his magic on NioDatagramWorker.

SyslogUDPSource is not using NIO to handle UDP (It's using OioDatagramChannelFactory), so NioDatagramWorker is not been used. 

I don't know if it's better to change netty server to work with NIO on SyslogUDPSource, or to put 64k as buffer initial value.
