>                 URL: https://issues.apache.org/jira/browse/DIRMINA-1040
>             Project: MINA
>          Issue Type: Bug
>          Components: Filter
>    Affects Versions: 2.0.4
>         Environment: Mina 2.0.4 version
> pl-1@ECE8000-Z1 ~ # /usr/java/latest/bin/java -version
> java version "1.6.0_45"
> Java(TM) SE Runtime Environment (build 1.6.0_45-b06)
> Java HotSpot(TM) 64-Bit Server VM (build 20.45-b01, mixed mode)

> 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);
