I've been trying to up my TCP window size from the default 16K and it's caused nothing but problems.  From the info I've found so far, these are the sysctl i've changed:

kern.ipc.maxsockbuffer=2097152
net.inet.tcp.rfc1323=1
net.inet.tcp.sendspace=524288
net.inet.tcp.recvspace=524288

But if I do that, on boot I get all sorts of error messages about buffer space.  i.e.:

Jul  9 11:53:20 ccn64 portmap[180]: cannot create tcp socket: No buffer space available
Jul  9 11:53:21 ccn64 inetd[199]: shell/tcp: socket: No buffer space available
Jul  9 11:53:21 ccn64 inetd[199]: login/tcp: socket: No buffer space available
Jul  9 11:58:55 ccn64 RPC::PlClient[243]: Cannot connect: No buffer space available 
Jul  9 11:58:55 ccn64 RPC::PlClient[246]: Cannot connect: No buffer space available

Is there anything I'm missing?
