You could use alarm() and signal() to catch a loop.

Psuedo-code:

1) interp.c

char last_command[MIL];

in interpret() add:

        strcpy(last_command, logline);

2) comm.c

add:

void sigalarm(int sig)
{
        time_t tm;
        extern char last_command[MIL];

        time(&tm);
        
        if((tm - current_time) > (60 * 2)) /* nothing for 2 minutes */
        {
                log_string("Mud inresponsive for 2 minutes, performing
reboot.");
                logf("Last command: %s", last_command);
                /* 
                   Use copyover if you want instead 
                   do_copyover(NULL, "");
                */
                exit(1);
        }
        alarm(60 * 2);
}

and in main or the top of game_loop_xxx add:

        signal(SIGALRM, sigalarm);


might help.
