We receive large amounts of UDP multicast data ... our buffers seem to be too small as we lose a few packets quite often (most likely due to scheduling). How do I adjust the size of the OS level UDP receive buffers?
equivalent of ...
sysctl -w kern.ipc.maxsockbuf=xxxxx in BSD
In running a netstat I am seeing
UDP Statistics for IPv4
Datagrams Received = 66550148
No Ports = 64212
Receive Errors = 0
Datagrams Sent = 5810
So perhaps the buffer size is not a problem?
We are also seeing alot of packet address errors (any suggestions on progressing on this?)... netstat-s included
