Spring Integration message channel hangs even if time out exceeds -

my integration context follows :

<int:channel id="fileinboundchanneladapter"/> <int-file:inbound-channel-adapter directory="${directory}" channel="fileinboundchanneladapter" auto-startup="false" >     <int:poller fixed-rate="5000" max-messages-per-poll="1" /> </int-file:inbound-channel-adapter> 

and manually triggering channel after condition met:

@resource(name = "fileinboundchanneladapter") private messagechannel messagechannel; 

inside method

message<file> filemessage = messagebuilder.withpayload(fileobject).build(); boolean success = messagechannel.send(filemessage, 1000 * 60); 

at line, messagechannel.send doesnot respond after time out exceeds , no other request served, , needs restart server.

you must share subscriber fileinboundchanneladapter. having try understand what's going on. , take logs figure issue side.

timeout param (1000 * 60 in case) doesn't have value directchannel:

protected boolean dosend(message<?> message, long timeout) {     try {         return this.getrequireddispatcher().dispatch(message);     }     catch (messagedispatchingexception e) {         string description = e.getmessage() + " channel '" + this.getfullchannelname() + "'.";         throw new messagedeliveryexception(message, description, e);     } } 

so, looks subscriber blocks calling thread somehow... need see code.
