Abstract
Embodiments are directed towards resynchronizing the processing of a monitored flow based on hole detection. A network monitoring device (NMD) may be employed to passively monitor flows of packets for a session between endpoints. The NMD may receive copies of the monitored flow and perform processes on the monitored flow. In some situations, some copies of packets may not be fully processed by the NMD, creating a hole in the processing. If a hole is detected in the monitored flow and the processing of the monitored flow is desynchronized, then the NMD may suspend processing until it is resynchronized or for a remainder of the session. If the processing is desynchronized, then the NMD may resynchronize the processing by resuming the processing of the monitored flow at a downstream position of the monitored flow based on the detected hole.
