Hi,
I was looking at TCP packets on wireshark and I found that during a download the advertised window in an ack packet was exceeding the max value of tcp_rmem parameter. What could be the reason for that?

Thanks

 The exact values are as follows:
tcp_rmem(min,default,max) = (4092 , 87380 , 704512)
The advertised window in the ack packets is ranging from 4092 till around 1,700,000
