azure-sdk-for-go: [azservicebus] Timeout in ReceiveMessages

Bug Report

• pkg: github.com/Azure/azure-sdk-for-go/sdk/messaging/azservicebus

• SDK version: v0.3.2

• go version: go 1.16.2

• What happened? We recently moved from azure-service-bus-go and implemented an asb client using azure-sdk-for-go. This implementation was working fine for few days and then started to give below timeout error frequently. A manual service restart seem to fix the issue temporarily, but after some time error appears again in the logs. Our implementation is supposed to retry retrieving messages indefinitely but it doesn’t seem to recover from the error and getting the messages from the topic. Pls note we are subscribing to multiple topics using multiple clients here. You can find our client implementation here. Error:

  Failed to receive messages from ASB. read tcp 1*.*.*.113:xxxxxx->**.*.*.88:xxxx: i/o timeout
  

• What did you expect or want to happen? If something unexpected causes this timeout error we expect it to recover when retrying.

• Anything we should know about your environment. Our service is running on AKS
