Underlying connection was closed

[samy]

I have an application which invokes(calls) a webservice (on IIS 5.0 , windows 2K) every 10 seconds.
After a long time(about 4 hours),the call to the webservice fails with the error

System.Net.WebException: The underlying connection was closed: An unexpected error occurred on a send
at System.Web.Services.Protocols.WebClientProtocol.GetWebResponse(WebRequest request
at System.Web.Services.Protocols.HttpWebClientProtocol.GetWebResponse(WebRequest request
at System.Web.Services.Protocols.SoapHttpClientProtocol.Invoke(String methodName, Object[] parameters
at ..


Any suggestion
