from dbaccess it is the same problem (run up to an hour and kills the
unix-performance)
the explain shows some sequential scans when the update(s) runs for
all entries or when the where-clause goes over the temp table columns
whitout an index.
We have testet with some indexes (seq. scans replaces with index path)
but nothing helps ... the session require too many - whatever
