The error 'invalid argument' is returned by mmap if fd is wrong or if the 
memory is not paged aligned if MAP_FIXED is specified (see man mmap). The
fd should not be wrong otherwise the server would exit earlier and
MAP_FIXED is not specified at the mmap call in the server. 

Therefore it should normally not happen. :-(
The only what I can think about is that there are changes at the kernel
which cause this behavier. The server did its work once.
Maybe a rebuild of the server will fix this. I can build a new server,
but I have no TT to test it.

This should be enough, you are right.
