I have problems when I want to execute the wrfpost.exe in my PC  
I compiled the WPPv3 without problems. I'm using FEDORA 8 in 64 bit  
and the PGI v7.2 compiler. My computer is a Quad-Core Intel XEON  
E5420(2.5 Ghz) with 8 cores and 4Gb of RAM.

I saw in the WRF forum that some people have had the same problem but  
I couldn't found any solution  

Here are the errors:
   + cat
   + 1> itag 0<< \EOF
   + rm fort.110 fort.14
   + ln -sf wrf_cntrl.parm fort.14
   + ln -sf griddef.out fort.110
   + /home/cenma/WRF/WPPV3/exec/wrfpost.exe
   + 0< itag 1> wrfpost_d01.000.out 2>& 1
   ./run_wrfpost_v0: line 154: 23834: Memory fault

Line 154 is ${POSTEXEC}/wrfpost.exe < itag >  wrfpost_${domain}.$fhr.out 2>&1

If I tried to execute using the mpirun command: I have
   + mpirun -np 8 /home/cenma/WRF/WPPV3/exec/wrfpost.exe
   + 0< itag 1> wrfpost_d01.000.out 2>& 1

I have this error in the .out file:
   /opt/pgi/linux86-64/7.2/mpi/mpich/bin/mpirun.ch_p4: line 243: 23802  
Violació de segment    /home/cenma/WRF/WPPV3/exec/wrfpost.exe -p4pg  
-p4wd /home/cenma/WRF/runs/andorra-1km/Nord_MP3/2009021012/wppv3/postprd

Any suggestion to solve the problem would be appreciate.
I also add my system limitations may be this information can help to  
solve the problem.
