      Description

      Background:
      our app messaging-server is to handle the SMPP protocol messages, and we use Mina 2.0.4 for the lower TCP transport function.

      Problem:
      sometime, not often, I found that the PDU could be truncated by Mina from tcpdump. I added some debug loggers to mina codes, and found that indeed the PDU truncated is occuring at Mina.

      from below logs, you can see in #3, the buf which got from WriteRequest got truncated the first 16 bytes in Mina. could you know if it's a known issue in 2.0.4?

      Debug loggers & Logs:
      1. IoHandler:
      WriteFuture future = iosession.write(deliverSm);
