My reporting service hung. I found that SQLDmprxxxx.log and SQLDmprxxxx.mdmp files are generating every 30 minutes in Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\LogFiles directory.
I don't think it is normal for any health service generates such a large amount of dump files. But I don't know what is wrong. Could somebody give me any advice on how I should troubleshooting the problem? One section of message in the log file is as below,
