Symptom: The NACK suppressed alarm is triggered in the mcast receiver , the receiver would stop receiving the files through multicast. Conditions: In case of the late joining receivers, if almost all the files have already been distributed, the NACK list sent out to the mcast sender is huge. When a huge number for the concurrent session is set, the mcast sender sends out huge amount of data. The multicast receiver is not capable of handling the huge amount of data. There are instances when for each job, the lifetime timer expires in the receiver, incrementing the failure count. When the failure count of file reception increases beyond a treshold , and bytes lost count exceeds its threshold- The unicast receiver (that also monitors the multicast stats) raises this alarm.
