Context is everything...

Where did you see this message? In the putty window? On the console of the linux box? In the error logs?

Did the connection complete? Were you able to type in some commands before you got the error?

There are several possibilites.

1) A bug in putty. Not likely because a quick look at the putty source shows no file make_cmd.c

2) A bug in your server code (I assume openssh). Possible. With a slow internet connection, I can't take a quick look at that, too much downloading going on..

3) A bug in a command that you're running.

4) A hardware error.

5) A configuration error.

6) Evil hackors own your box.

Having used putty to log into many linux boxes, but with no knowledge of the inner workings, my guess would be option 5 is most likely. If you have access to newsgroups, try posting to comp.security.ssh with as much info as you can.
