Comment 0 for bug 1412693

From a customer's SHOW ENGINE INNODB STATUS samples, we found one transaction first in ROLLING BACK and then continued on. I never encountered this before and don't know how to reproduce it. But the customer sees ROLLING BACK in the transaction section for this query from time to time.
