I have an error and I do not know why ?

I try to execute the example: t2d_malpasset-large.cas
It runs fine with single Processor but I get the following error when try to run with two processors or more. What is wrong with it ?

partitioning: T2DREF
+> /usr/local/telemac/v6p2/v6p2r1/parallel/parallel_v6p2/fedgfopenmpi/partel < PARTEL.PAR >> partel_T2DREF.log
sh: line 1: 5293 Segmentation fault (core dumped) /usr/local/telemac/v6p2/v6p2r1/parallel/parallel_v6p2/fedgfopenmpi/partel < PARTEL.PAR >> partel_T2DREF.log
... The following command failed for the reason above
/usr/local/telemac/v6p2/v6p2r1/parallel/parallel_v6p2/fedgfopenmpi/partel < PARTEL.PAR >> partel_T2DREF.log

My Environment:
CentOS 6.4 with gfortran-4.4.7-3.el6.x86_64
OpenMPI 1.6.4

phuongTelemac	Thanks for your remind. I think that is the problem because I use metis 4.3. I will upgrade it now.
