ipv6 disabled on this kernel module.

The FD ( file descriptor ) table is mem . so i was thinking if  that 
could be a memory issue. But i think i need to know some basic 
explanation of what might be the causes of this .. i doubt .. some 
libraries being unlinked such that the process is trying to find the 
same and is not being able to find it .

I would really appreciate to learn more about this .. and if anyone of 
you have faced similar problems before. .
