Embodiments of the present invention relate to detecting and rectifying corruption in a distributed clock in a distributed system. Aspects may include receiving a sequence number used as part of the distributed clock at a node and determining if the sequence number is corrupt. In order to provide an effective mechanism for determining a sequence number is corrupt and taking corrective actions, a valid sequence number range may be determined, a propagation count associated with the sequence number may be evaluated, an estimated sequence number may be calculated, and an epoch number associated with the sequence number may be evaluated. Additionally, in exemplary aspects node with a corrupt trusted sequence values may self diagnosis and terminate associated processes to prevent further propagation of the corrupt sequence number. |
