Mark Swanson commented on DIRSERVER-926:
----------------------------------------
The problem must be that cfg.isReuseAddress() == false
In Mina 1.0.0:
core/src/main/java/org/apache/mina/transport/socket/nio/SocketAcceptor.java
About line 426:
// Configure the server socket,
SocketAcceptorConfig cfg;
if( req.config instanceof SocketAcceptorConfig )
{
cfg = ( SocketAcceptorConfig ) req.config;
}
else
{
cfg = ( SocketAcceptorConfig ) getDefaultConfig();
}
ssc.socket().setReuseAddress( cfg.isReuseAddress() );
ssc.socket().setReceiveBufferSize(
( ( SocketSessionConfig ) cfg.getSessionConfig()
).getReceiveBufferSize() );
// and bind.
ssc.socket().bind( req.address, cfg.getBacklog() );
Maybe as a quick check we could walk backwards from this point and figure out
why this is false.
Ok, I ran this through the debugger and isReuseAddress() == true.
The only possibilities I see are:
1. setReceiveBufferSize() is changing reuseAddress. unlikely
2. Java 6 bind() ignores reuseAddress. unlikely
The Java 6 changelog doesn't give any indication, and I couldn't find any help
from Google.
I'm out.
Cheers.

> Project: Directory ApacheDS
> Issue Type: Bug
> Affects Versions: 1.0.1
> Environment: Java 6 build 105, Linux CentOS 4.4.
> Reporter: Mark Swanson
>
> Shutting down ADS leaves all existing connections in FIN_WAIT1. This isn't a
> problem.
> However, when starting up ADS again any previous connection still in
> FIN_WAIT1 will prevent ADS from starting.
> The only workaround is to wait until all FIN_WAIT1 connections timeout and
> get closed by the OS.
> On the mailing list Emmanuel already checked this:
> This is already done :
> ...
> try
> {
> // Disable the disconnection of the clients on unbind
> SocketAcceptorConfig acceptorCfg = new SocketAcceptorConfig();
> acceptorCfg.setDisconnectOnUnbind( false );
> acceptorCfg.setReuseAddress( true );
> ...
> The 100% reproducible stack trace when existing FIN_WAIT1 connections are
> present:
