Dear netters,

When I'm debugging a parallel C program and want to look at the contents of
variables on processors other than the first processor, I sometimes get the following
reply:

can't read from data address 0x2f000000

What could be the problem ?

Configuration:
   Sequent Symmetry
   Number of PE's = 8
   DYNIX V3.1.4 NFS
   Debugger: pdbx

The processes read and write from a shared global memory, which is allocated by
the first processor before the 'm_fork()'.
I still can step through my program, but I can't print values.


Thanx in advance.
