When system limits are exceeded, the operating system advises you by displaying messages on the console. Some of the messages are advisory only. Others precede a system panic: the system displays some additional diagnostic messages and then ``hangs,'' requiring you to reboot.
If you are running X, these messages may not appear on your console. If your system hangs, switch to the console multiscreen by pressing <Ctrl><Alt><F1>, if possible, and read the diagnostic messages. If you cannot switch multiscreens, reboot the system and read the messages in the /usr/adm/messages and /usr/adm/syslog files.
If you use multiple servers (X terminals or console multiscreens) with an SCO OpenServer system, you may need to reset some system parameters. See ``Kernel parameters that you can change using configure''.
