error message in parallel
 

I run fluent 6.3.26 in parallelm I have 2 pc [2*4core] with 2*8Go Ramm with mpich2 and I hqve this error [you know thanks for help...] my OS xp 64 bits SP2 on each pc [firewall unactivate] switch gigabit ethernet

Checking the status of SMPD for MPICH2 on the local machine ... '\\NT-1BEE049B35EB\codedol20C'

I have partially resolve my problem with the environnement variable:MPICH2_CHANNEL

but now, I have a new error message, I use the model discrete ordinate and I change the DO by scheme to accelerate the calcul.
After 3 ou 4 changing of DO --> BOOM ERROR

ex: do 1 1 1 1--->ok
do 2 2 2 2--->ok
do 3 3 3 3--->ok
do 4 4 4 4 --->ok
do 5 5 5 5 ---> error

or other example:
do 2 2 2 2 --->ok
do 4 4 4 4--->ok
do 6 6 6 6--->ok
do 8 8 8 8 --->ok
do 10 10 10 10 ---> error

example for the error message:
