I have read the description but can't find anything which points that this is
related to T platform.
Are you sure that this bug wouldn'd happen if run on M series ?
This is more related to number of session and processes (Solaris level) then to
hardware.
Also this database works on ZFS - personally I wouldn't recommend ZFS for
highly transactional Oracle.

Well, our case might not say anything but we use T series quite intensive
(also benchmarked them to be fully 100% loaded) and are quite happy
with its result (but typical OLTP workload). Though at the moment of purchase
I guess there wasn't Nehalem-based servers ...
