Hi All,

<>Please ignore the first message, it is incomplete<>

I am getting the following exception in my server logs after about 2-3
minutes of uptime. Please help me in indentifying the solution for
this issue:

I am not sure, but It looks like messageReceived is fired before
SSLHandshake is finished.

Some more information:
1. I am doing some DB operation in my channelConnected method (p.s.
the operation are done within the FutureListener).
2. I am using Netty 3.1 Beta 2.
3. JDK 1.5.0_11, Solaris 10 on a SPARC system.

My handler.channelConnected() looks something like below:

public void channelConnected(...)
{
 // get SSLHandshake furure = handshakeFuture
 handshakeFuture.addListener(new ChannelFutureListener(){
 public void operationComplete(...){
   if(isNodePresentInDB())
      //accept the connection and add the channel to channel group
   else if(isConnectionFromLocalInterface())
    // accept the connection and add channel to channel group
   else
      //connection is from a invalid node, ignore the connection and
close the channel.
}

Please let me know if any further information is required.

Thanks,

Virat
