message is remaining inside queue even if evnt notification is present and service is also running , in service broker external activator

Hi,

I doing work on service broker external activator, all are working fine , but if i insert data , its is remaining in thq queue, even when the event notification is present , given grant permission , config , app.config everything is correct.

if i turn off service , end task , then turn on service , then it will work fine , queue will be cleared . but then when i insert data again , its remaining in queue. 

can anyone help...

Thanks in advance
