To clarify it first run only lots of SMWRefreshJobs. After that reached prog=1 it started running both SMWRefreshJobs (with smaller prog) and lots of SMWUpdateJobs with multiple threads.

What is the status on this ticket? If the problem still persists with the current master, are they any suggestions how to solve this issue?

This is still the case. Unfortunately I do not know how to fix it. Adding Aaron to CC in case he has ideas.

Just to clarify, since we have to support MW 1.19 we can't do any fancy stuff that is implemented by the new JobQueue class (as in 1.21/1.22) therefore the current code is as simple as:

class SMWRefreshJob extends Job {
	...

	$nextjob = new SMWRefreshJob( $this->title, array( ... ) );
	$nextjob->insert();

	...
}
