 ### Troubleshooting Cloud Services
 For roles in Cloud Services, the default temporary folder may be too small to hold the minidump files, leading to lost snapshots.
 The space needed depends on the total working set of your application and the number of concurrent snapshots.
 The working set of a 32-bit ASP.NET web role is typically between 200 MB and 500 MB.
 Allow for at least two concurrent snapshots.
-For example, if your application uses 1 GB of total working set, you should ensure that there is at least 2 GB of disk space to store snapshots.
