Why does a service rescan take so long?

I'm using v. 1.12.1 and provisiond.

If I use the "rescan" function on node's website an "A services scan has been forced on this node"-event will be created. But after 60 minutes there is still no rescan completed event. But why? How does a rescan work?

That is abnormal.  Check your system's resource usage (memory, cpu, disk io, interrupts, jvm stats).  Also check logs- uncategorized, output, misc, and turn up DEBUG on provisiond logging before you initiate a rescan.  

You might upgrade to 1.12.4.  Numerous bug fixes since then.

The resource usage was ok. I've updated to 1.12.5. The abnormal rescan duration is now gone. Maybe a bug..
