Xavi,

According to the source code, the message "exec0(48): returning due to  
error" is generated when one of three calls to pipe() fails. The most  
likely reason that this fails is that are no file descriptors  
available, and the other error you are seeing about "Too many open  
files" also points to a file descriptor shortage.

Since the only non-standard thing you've done is add a ETFw script, I  
wonder if this has something to do with it? Can you disable the script  
and see if you still have problems?
