Description

Mina version:

mina-core-2.0.19.jar

Server code snippet:
        IoAcceptor acceptor = new NioSocketAcceptor();
        DefaultIoFilterChainBuilder chain = acceptor.getFilterChain();

        LoggingFilter loggingFilter = new LoggingFilter();
        loggingFilter.setMessageSentLogLevel(LogLevel.DEBUG);
        loggingFilter.setMessageReceivedLogLevel(LogLevel.DEBUG);
        loggingFilter.setSessionClosedLogLevel(LogLevel.DEBUG);
        loggingFilter.setSessionCreatedLogLevel(LogLevel.DEBUG);
        loggingFilter.setSessionIdleLogLevel(LogLevel.DEBUG);
        loggingFilter.setSessionOpenedLogLevel(LogLevel.DEBUG);
        chain.addLast("logger", loggingFilter);

        MdcInjectionFilter mdcInjectionFilter = new MdcInjectionFilter();
        chain.addLast("mdc", mdcInjectionFilter);
        chain.addLast("codec", new ProtocolCodecFilter(new ObjectSerializationCodecFactory()));

Client code snippet:
        NioSocketConnector connector = new NioSocketConnector();
        LoggingFilter LOGGING_FILTER = new LoggingFilter("MinaLogging");
        LOGGING_FILTER.setMessageSentLogLevel(LogLevel.DEBUG);
        LOGGING_FILTER.setMessageReceivedLogLevel(LogLevel.DEBUG);
        
        IoFilter CODEC_FILTER = new ProtocolCodecFilter(new ObjectSerializationCodecFactory());

        connector.getFilterChain().addLast("mdc", new MdcInjectionFilter());
        connector.getFilterChain().addLast("codec", CODEC_FILTER);
        connector.getFilterChain().addLast("logger", LOGGING_FILTER);

Exception:
org.apache.mina.filter.codec.ProtocolDecoderException: org.apache.mina.core.buffer.BufferDataException: dataLength: 1048985 (Hexdump: XX...)

Points:

• There is no synchronization while writing...
• There are multiple threads parallely wirting into the tcp connection (around 100-200)
• The problem is observed only when the load is high...

I have seen similar tickets here and not sure about the RCA.

Need help...
