HttpAdapter – BizTalk 2013 – no response when exception Occurs

We have a problem: We are send message using webHttp componet to  biztalk http port (BTSHTTPReceive.dll)

Configuration for http port as follows

Virtual directory plus ISAPI extension = “path/BTSHTTPReceive.dll”

Suspend Failed Requests = true

this port is request – response port and  two pipeline and  Receive pipeline inclused the ESB itinerary for further process.

However, if any exception

Occurs

One Static – one Way SQL Port is defined with filter condition like

ErrorReport.FailureCode

Exists  

Microsoft.Practices.ESB.ExceptionHandling.Schemas.Property.FaultCode

Exists

 But when exception occure SQL port capture the execption and make entry in database, and no respose is sending to WebHttp compoent, which is wating for a response thus the webhttp conponent get timeout,

 what is the reason for this behaviour,

Please help me.. thanks in advance
