Many thanks, Johnatan - with this info I hope, quite well established what happened and possibly how to prevent this in future - seems _rollback_segment_count would enforce initially a higher number of undo segements, thus raising the total possible number of concurrent transactions


p.s. sorry to not cut the answers, but not sure how to enforce gmail not to attach previous mail in the text
