…p failures and 'key not found' errors (#50766)

Related PR: #50037 

If an error occurs during transaction label recycling, the vector
recording keys cannot be cleaned up. Keys that were already cleaned up
in the previous scan and recycle cycle will be carried over to the next
scan and recycle cycle, causing a large number of 'key not found'
errors.
