Ok, thanks for reporting this. It's probably a bug that parallel replication
behaves differently from non-parallel. I'll try to look into it when I have
time.

I could imagine that there are more bugs lurking when the log counter
overflows... I'm not sure this is well tested. I wonder what the "correct"
behaviour is? Should it just continue with slave-relay-log.1000000 ?

Thanks,
