I'm getting the exception is mentioned in the subject. I found also
two threads with the questions, but there is no suggestion on how to
handle it. Should I catch it and retry? Should I catch it and schedule
a task? Is there anything I should check in my application? Any other
suggestion?
Thank you in advance for any help!
