I am using MariaDB 10.0.14 at CentOS 6.5.
And, as I mentioned at the title of this question, the relay-log is not
flushed after the slave-relay-log.999999 showed when using
"Salve_parallel_threads:10" setting. like showed blow.
- binlog_format: ROW
- Slave_parallel_threads:10
Everything are working fine except the "slave-relay-log.******" files
continue to exist at the disk which will finally cause the disk full.
If I change the value of Slave_parallel_threads setting from 10 to 0,
the log will be flushed. Howevery "PK duplicate warning" error logs come
next.
Is there any setting should be used with Slave_parallel_threads setting?
Any help will be great.
Best regareds,

Bug
Critical
I also came into this issue a few days ago, and I have located this bug and fixed it, I've attached my patch here.
The problem is that in Relay_log_info::inc_group_relay_log_pos() function, they way you compare two log name is via strcmp() function, this is fine when log name sequence number are both of the same digits( 6 digits). but when the number goes to 7 digits, a 99999 compares greater than 1000000, which is wrong, hence the bug.
Besides this bug, I also located another bug caused by the same mistake in handle_queued_pos_update(), which could cause parallel replication issues when log name sequence number goes to 7 digits.
