# BUG#28421 Infinite loop on slave relay logs

# That, manually deleteing one or more entries from 'master-bin.index', will
# cause master infinitely loop to send one binlog file.
# 
# Manually changing index file is a illegal action, so when this happen, we
# send a fatal error to slave and close the dump session.

# (master-bin.000002) is the last binlog file, so master is waiting for new
