Subject RE: Graceful shutdown sequence
Date Fri, 08 Nov 2013 22:28:25 GMT
Not sure if this helps but 

When the shutdown request is sent. 

At org.apache.mina.filter.executor.UnorderedThreadPoolExecutor:476  
ran=true 

and this is content of task object. 

[(0x00000001: nio socket, server, null => /127.0.0.1:10389)] MESSAGE_RECEIVED: MessageType
: EXTENDED_REQUEST
Message ID : 2
    Extended request
        Request name : '1.3.6.1.4.1.18060.0.1.3'
org.apache.directory.api.ldap.extras.extended.GracefulShutdownRequestImpl@2a5eb8cf

Thanks.

Hi Emmanuel,  When the server is running, these are the threads. 

org.apache.directory.server.UberjarMain at localhost:62236	
	Daemon Thread [apacheds] (Running)	
	Daemon Thread [changePwdReplayCache.data] (Running)	
	Daemon Thread [kdcReplayCache.data] (Running)	
	Daemon Thread [ou=system.data] (Running)	
	Daemon Thread [groupCache.data] (Running)	
	Daemon Thread [Thread-1] (Running)	
	Daemon Thread [Thread-2] (Running)	
	Thread [NioSocketAcceptor-2] (Running)	
	Thread [NioSocketAcceptor-1] (Running)	
	Thread [DestroyJavaVM] (Running)	


Then I call the shutdown code from my previous message and they are all still running along
with DestroyJavaVM.
If I suspend DestroyJavaVM, there's nothing it its call stack.

	Thread [DestroyJavaVM] (Running)	
	Thread [pool-2-thread-1] (Running)	
	Thread [pool-7-thread-1] (Running)	


However, if I try to call the shutdown code again, the exception below is thrown.  Thanks..

Hi Carlo,

any idea on which thread remains up and running ?
