If you have access to the ANALYZE scripts, could you modify it to obtain _what_ this session is waiting for and how much (from V$SESSION_EVENT) as well as look at V$MYSTAT to determine the volume of work. It would be a good idea if you can back-test (is there such an equivalent for back-port?!) on the older environment. This may give us some clues.... I am not aware of ANALYZE changing, although the CBO decisions between the two versions (given the same stats/values) may differ.
