  Alrighty, but thats still kind of vague..  You reading in the file, and then 
going to add it as cdata to a tag in the result?

  You could do pretty much what mod_time does, which is to use jutil_iqresult 
on the packet, set the namespace for the query, then reset the packet for 
delivery.  That way your reusing the already created tag, but up to you, 
really, either way will work, be it make a new one, or resuse the existing one..

  Need more data on this one, your question confuses me a bit.  Can you paste 
some psuedo code or snippets to show what you did that caused the core dump?

  Take a look at mod_time, which is a really good SHORT example of a module 
that replies to an iq message, it may help a bit if what you are doing is 
relativly simple..  Seems to me all it sounds like your doing is reading a 
file, and attaching it as a cdata segment, but that might not be what your 
trying to do..
