.NET Forum / ASP.NET / Web Services / September 2006"The operation has timed-out" happening intermittently
Hi I have a .Net 1.1 Web Service "A" calling into another Web Service "B". Calls from A to B work fine for most of the time but intermittently I get a "System.Net.WebException" with the message "The operation has timed-out". There is no log of this request on B's IIS. Normally the calls from A to B take only about 300 ms to be processed but when the exception occurs it seems that A waits for about 100 seconds before throwing the WebException. The Service A is on a Windows 2000 box with IIS 5.1 and the Web Service B is on Win 2K3 with IIS 6.0. Any suggestions will be appreciated. Sandeep, Did you check the following 1. Is the service B doing some operation involving Data Access 2. If so check whether there is any problem with the database interaction 2. Is service B doing some operation consuming resources 3. Whether service B is sporadically unavailable ? 4. Whether service A is not able to make calls to the sevice sporadically ? 5. Just also check whether connectivity between Service A and Service B is sporadically unavailable ?

Service B when tested using a non WebService client ( but with the same data as A would call it ) always responds quickly no matter how many times it is called. There are no network issues between A and B. The calls from A that fail with the time-out issue do not show up on Service B's IIS logs at all. So it almost seems like they never make it out of Service A's machine. One think I failed to mention is that Service B is set for Integrated Authentication in IIS. > Sandeep, > [quoted text clipped - 17 lines] > > Win 2K3 with IIS 6.0. > > Any suggestions will be appreciated.
