WebbThe value for retransmit timeouts occurs when TCP sends a packet but does not receive an ACK in time. It then resends the packet. This value is incremented for any subsequent retransmittals. These continuous retransmittals drive CPU utilization higher, and if the receiving node does not receive the packet, it eventually will be dropped.
