Arthur, the developers believe they have a fix for ER-2285 that more matches your call trace.

The 9.10 MR1 will include the change, but if you're willing to try it (*with patch code caveats)

please open a Tech Support ticket and ask for Michael Brado.  The engineer who says he has

the fix will provide the test build, if you let us know what platform of ZoneDirector you have.

Not obvious, but Engineering calls it kernel panic, application reboot.
