Error using the infoUSA mailing list webservice

[Ashish Gupta via .NET 247]

Hi Guys

I am using mailing list web service of infoUSA.com.
Sometimes it gives the following error :

System.Web.Services.Protocols.SoapException: Server was unable toprocess request. ---> System.IO.IOException: The process cannotaccess the file "\\arwen\share\listbazaar_logs\sms_live.log"because it is being used by another process. atSystem.IO.__Error.WinIOError(Int32 errorCode, String str) atSystem.IO.FileStream..ctor(String path, FileMode mode,FileAccess access, FileShare share, Int32 bufferSize, BooleanuseAsync, String msgPath, Boolean bFromProxy) atSystem.IO.FileStream..ctor(String path, FileMode mode) atIUSA.Web.Database.SMS.Send(String request) atIUSA.Web.Database.SMS.Term() atIUSA.Web.Database.SMS.Disconnect() atinfoUSAlistconnect.Service.ListConnectSession.SetLayout(StringLayoutType, String OutputType) atinfoUSAlistconnect.Service.listconnect.SetLayout(StringSessionID, String LayoutType, String OutputType) --- End ofinner exception stack trace

I emphasize on the point "Sometimes".
What needs to be checked at my end (as i dont have the access tothe source code of the web service) ?

Thanx in advance
Regards
Ashish

Ashish,

1) try running Filemon and look at what is the other process using sms_live.log
2) if you are reading and writing from/to a file at the same time, make sure you have specified FileShare.ReadWrite, which allows a file to be read and written to
at the same time.

Hope that helps,

Michelle
