Thanks to all who replied off-list. We tried some of the approaches and
we haven't got anything specific, but we detected some secondary issues
in the process, like the one noted here

During the testing we caused a crash due to a Segmentation Fault on line

if (engine->workers[i]->task &&

Situation: engine->workers is NULL.
How: I have no idea but it might be related to the assertion

For this case I have a core dump which I'm sending to OpenDNSSEC developers.
