However what is says is how to set the udp max buffer size: # ndd /dev/udp udp_max_buf 1048576 which according to http://docs.sun.com/app/docs/doc/806-6779/6jfmsfr8b?a=view sets the "maximum allowed buffer size for an udp socket", not the actual value. The default receive buffer size is set using the parameter udp_recv_hiwat which is currently set to its maximum value of 65536. To increase it the only way is the setsockopt syscall. Anyway I don't get that many udpInOverflows (a few everyday) but it does not explain the few thousand messages I miss in my logs files. Regards, Vincent. -- .~.
