Well, you say the commands run, they just don't produce any output.  I'm 
hoping strace will be different (although, that is a bit unlikely).

In any case, it looks like your shell is have problems exec()-ing commands 
while env and echo are probably built-ins.

Perhaps your nproc ulimit is to low... or maybe it's something entirely 
different.

Try:
ssh host strace ls
ssh host exec ls
ssh host exec strace ls

And see which ones produce output and how the outputs differ.  With the 
outputs if you need any more assistance.
