Jens,

It appears that a problem I saw earlier may be related.

I get passed the login, and actually get the login message.  But at that
point, id.exe locks up the machine, grabbing, as in your case, 100% of CPU.

Running ps -aef shows the following at the time we lock up:

$ ps -aef
     UID     PID    PPID TTY     STIME COMMAND
administ     628       1  -1  12:59:30 /usr/bin/bash
  system     568       1  -1  13:10:30 /usr/sbin/inetd
  system    1008     568  -1  13:10:30 /usr/sbin/inetd
administ     780       1  -1  13:11:16 /usr/bin/bash
administ    1420     628  -1  13:12:01 /usr/bin/telnet
  system    1304    1008  -1  13:12:01 /usr/sbin/in.telnetd
administ    1428    1304   0  13:12:30 /usr/bin/sh
administ    1140    1428   0  13:12:30 /usr/bin/id
administ     380     780  -1  13:12:36 /usr/bin/ps

I'm guessing that id does not get a tty, and blocks on stdout.  Worse, it
burns CPU when it does so.

I'll try building id.exe debug to see if this is true, but unless I can
figure this out, I'll also drop down to cygwin 1.1.8.

So any luck at your end?

Thanks,
Rob

 Hi,

 I've been looking around the threads on this list. And have not 
found any thread that seems to be about the same problem. So I ask 
here now.

 I did download the cygwin 1.3.1 with the setup program. And I 
installed it. And then telnetd stoped functionen. I thought OK. It's 
time for me to do a reinstall of everything. So I uninstalled 
everything. And removed everything from the regestry. And then I did 
a fresh install from the net. But I still have the same problem.

 When I do telnet to my machine now I get a in.telnetd.exe that is 
using 100% CPU time and I never get a login promt.

 When I reinstall the cygwin 1.1.8 it starts working again.

 What could be wrong?
 I hava WinNT 4.0 SP6 machine.
