The only processes running on the machine are the netacct and zebra's BGP and OSPF daemons. Before, we were running net-acct, collecting data via an AF_INET, SOCK_PACKET socket. I am not aware that this setup lost any data, but it was established before my time. The new net-acct uses PF_PACKET, SOCK_DGRAM instead, and this for sure loses data :-( > > Can the program learn if the queue has overflowed, so that it is able > > to yell at its admins for a larger queue?
