Question

I have created a one-time subscription in SSRS report manager 2008. However I keep getting duplicate emails sent out by the subscription. The interval between each email is about 30 minutes.

I have checked SQL agent job and it looks the SQL agent job is created correctly. It just runs once and after that the next run time is cleared.

I also checked SMTP service on local machine by testing code. SMTP works fine for test email without duplicate. So I guess probably it is something wrong in SSRS. Any advice on where I can look into?

Update on this problem.

When I enable the reporting service log, the problem never happens again.

To the configuration file, the following is added.

<system.diagnostics>     <switches>       <add name='DefaultTraceSwitch' value='3' />     </switches>   </system.diagnostics>    <RStrace>                   <add name='FileName' value='ReportServerService_' />                   <add name='FileSizeLimitMb' value='32' />                   <add name='KeepFilesForDays' value='5' />                   <add name='Prefix' value='tid, time' />                   <add name='TraceListeners' value='debugwindow, file' />                   <add name='TraceFileMode' value='unique' />                   <add name='HttpTraceFileName' value='ReportServerService_HTTP_' />                   <add name='HttpTraceSwitches' value='date,time, clientip,username,serverip,serverport,host,method,uristem,uriquery,protocolstatus,bytesreceived,timetaken,protocolversion,useragent,cookiereceived,cookiesent,referrer' />                   <add name='Components' value='all:3,http:4' />   </RStrace> 

However we are not sure if the problem is gone as well if we remove the configuration section. We don’t want to keep the log as it grows quite fast.
