Twice in the last two days I have had events that shows "failed to list, failed to post in time." The item also shows up in scheduled listings with a "not relisted" and "error message".
Having had this issue before, I made sure to check active listings prior to rescheduling the listings. Sure enough both items had relisted (one item from yesterday evening and another item the day before).
I am cautioning others to make sure to check events and failures to see if the item relisted or was listed despite the notice. That will protect users from getting a duplicate warning notice from ebay.
