> Mina 2.0.4 truncated the PDU
> ----------------------------
>
> Key: DIRMINA-1040
> 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)
> Reporter: Silver Cheng
> Labels: PDU, truncated
> Attachments: Mina-2.0.13-code delta.docx, apache-mina-2.0.13.zip, mina log and tcpdump.zip, mina-debug-logging.zip, ms-mc1.zip, tcpdump-10001.zip
>
>
> 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);
