This TruthValue flags that the sequence-discontinuity counter (cienaCesBenchmarkTestInstanceStatsRxDiscSeqNumPkts) has rolled over in hardware, so the reported gap count understates the true number of sequence discontinuities seen during a long test. An admin treats this exactly like the other overflow flags in this table: a signal to not trust the absolute counter value and to clear stats before drawing conclusions from it. For example, this flag reading 'true' on a week-long soak test would explain why the discontinuity count looks implausibly low compared to the amount of loss reported elsewhere.
