Hi, Micheal,

Thanks a lot for your help, but I still have one question.

In Octavia, once the controller worker fails plugging VIP to the amphora,
the amphora is deleted immediately, making it impossible to trace the
error. How to prevent Octavia from stopping and deleting the amphora?

Best regards,
Yipei
