Just to clarify: The entire IOS goes down, not only the terminal app.

No, it doesn't.
I attached a screenshot of me successfully using ps as mobile

I also tried as root, with same results

Looks pretty good on your device, I have to admit that...

However, I can reproduce it: The system goes down.
Unfortunately, I cannot make a screen shot once that happens :(

Some additional infos: 
1. The system is jailbroken using pwnage tool. 
2. Furthermore, I am not able to connect via ssh onto the phone since the 
update to 4.1 ... 
3. Pinging the device is also not possible.

Maybe these problems are somehow related.

OK, this seems device related.
Have you tried restoring your device?

If you can't ping 127.0.0.1 that's usually a very bad sign

Other commands do work: ls, cd, ..., ps --help also works

Somehow it seems that there is some random effect since I was able to execute 
ps -ef once successfully. Since then, about 5 retries crashed the system.

Do you mean restoring to a clean jailbreak state? I just did that yesterday, it 
is actually pretty much vanilla

FYI:
>$ ping localhost
... does work using mobileterminal!
I just cannot ping from a different computer in the network. This is the reason 
why I wanted to use ps, to see whether ssh is up and running.

Then maybe it's ssh's fault

If you're running on a aunix-system, try nmap to see the open ports

Its an OSX and I have also tried ssh from a Windows7 computer. 
Both are able to ssh onto other computers (e.g. one external server and also a 
virtual box Ubuntu 10.04 on the OSX), just not onto the iphone.

Maybe that's a hint:

>$ su root
-sh: fork: Resource temporarliy unavailable
>$ whoami
-sh: fork: Resource temporarliy unavailable

It seems to be a problem with my specific device! I just don't get what the 
problem might be... In general the Phone is working fine, this is why I 
actually do not want to restore to vanilla state :(

You could use tar to make a tarball of your /var/mobile or backup your phone in 
any way you can imagine,
then restore and re-install everyting step-by-step

A backup never made things worse

One last info, maybe someone has an idea: All ports that I scanned with nmap 
are closed (also the 22 for ssh). Open-ssh is installed, unfortunately I cannot 
check whether it is running since mobileterminal crashes as described above if 
I try to.

Thanks for your help... I believe it is not an issue with the terminal app!

Backing up via tar is not so easy if you cannot access the system ;)

Try installing sudo via Cydia

Anyways: It seems as if your system is broken in a way I don't fully understand.
Sorry
