AzureBlobTraceListener ThreadAbortException

Describe the bug

We're getting the following error when entries in the blob are generated. It is sporadic and seems like may be correlated with higher load.

To Reproduce

Create blob in the Azure Create snippet to log entries via log4net to the blob using AzureBlobTraceListener Code Snippet

Logger.Info or Logger.Error or Logger.Warn causes this.

Expected behavior A clear and concise description of what you expected to happen.

Screenshots If applicable, add screenshots to help explain your problem.

Setup (please complete the following information): 4.7.3324.0 built by: NET472REL1LAST_C

What version of the SDK are you using? And what APIs are you calling that are resulting in these exceptions?

[schmidtaa]

We're using log4net to log info messages and getting exceptions when we call methods: logger.Info(…) or logger.Warn(…) or logger.Error(…):

SDK or .Net which is running in app service : 4.7.3062.0 built by: NET472REL1
