Are we overstressing our Mac IIx? You can use kconfig to increase MAXCORE. The default is 128K. We increased our server to 256K and have not had any problems since. We have also set the following: NFILE=600, NINODE=600, NFLOCK=600, FLCKREC=600, FLCKFIL=150, NPROC=100. If you are using the KEEPALIVE option on sockets under A/UX 1.1, you will need to change the timing in the kernel to get the 10 minute timeouts of 1.0. We use adb to set tcp_keepidle to 0x96 (down from 0x3840), but there's no point in making that change unless you need it. --Jim Dr. James H.
