It was all default configuration. The pool was a RAID-Z2 without hotspare disk. The box is now running some other tests (not FreeBSD) at our Beijing Lab and we don't have remote hands in the nights, so I'm afraid that I will not be able to provide further information at this moment. Please let me know if the test run will not provoke the problem and I will ask them to see if they can spare the box in the weekend for me.
