I am using EventProcessorHost in webjob with multiple instances - giving exception Microsoft.ServiceBus.Messaging.LeaseLostException. Perticularly only one instance is giving this exception.
It is not giving any exception when I am running it as single instances
Microsoft.ServiceBus.Messaging.LeaseLostException: Exception of type 'Microsoft.ServiceBus.Messaging.LeaseLostException' was thrown. ---> Microsoft.WindowsAzure.Storage.StorageException: The remote server returned an error: (409) Conflict. ---> System.Net.WebException: The remote server returned an error: (409) Conflict.

I am reading messages one at a time. Please suggest.
I was able to avoid this by setting the Host name to be a unique string. For example
var eventProcessorHostName = Guid.NewGuid().ToString();
