OK. I figured it out: Im stupid. The Kiwi SyslogGen was set for random on the priority, and I was not logging .debug level logging. (info..emerg) So, as far I've experienced, Solaris * only really needs to have the udp receive high water mark raised to 64k: ndd -set /dev/udp udp_recv_hiwat 65536 All is well. -Wayne
