Default onbar -v very slow

Running IDS Version 9.40.UC5 on Redhat AS 3.0.

Onbar backup performance is great... verify performance is atrocious. We get
about 40M/sec on backup, but verify is taking about 45seconds/Meg. I've
searched and googled to no avail... has anyone seen similar or does nayone
know of a known bug?

Informix (IBM) identified this as a known bug (#439537) that has been fixed
in a recent release of IDS 10. They are creating a patch for our 9.40UC5
install.

I'd be very happy if "onbar -v" would work at least.
More than 50% of runs (point-in-time verification) it just core dumps and
that's it.
If I try to restore from such non-verified backup everything is fine,
onchecks don't report any problems (and neither do our clients :-)).
Hmmm...
