setsockopt is failing in:
while (setsockopt(s, SOL_SOCKET, SO_RCVBUF,
(void*)&bufspace, sizeof(bufspace)) < 0) {
if ((bufspace -= 1024) <= 0)
err(1, "Cannot set the receive buffer size");
}
if (bufspace < IP_MAXPACKET)
warnx("Could only allocate a receive buffer of %i bytes
(default %i)",
bufspace, IP_MAXPACKET);
Did you tweak any sysctl options ?
Is the machine loaded ?
I think sbchecklowmem() may be failing in uipc_socket2.c:403.
Also ping should use warn() instead of a warnx() there.
Claudio ?
