-------------------------------------
Summary: 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
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?
