- A common cause of this is filling the process table. Ping responses are
- done by the kernel, so they don't require a new process. Inetd accepts
- connections before trying to start up the server process; in the case of
- telnet, this means that telnetd can't run.
-
- Another possibility is using up swap space.
-
- However, I'd expect there to be messages on the console with something like
- "no more processes" or "no more memory". But if the console output is
- going to a window, the problem could be afflicting the window system as
- well, preventing it from displaying the message.
