Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation in ndown

Hello
I want run the WRF for a one-way nested simulation on a HPC. I have 3 domains with 27,9 and 3km resolution, I can successfully run WPS and real.exe, but when I run the ndown.exe I get this error:


Code:
Program received signal SIGFPE: Floating-point exception - erroneous arithmetic operation.

Backtrace for this error:
#0  0x2b95c62cf3ff in ???
#1  0x3a84e53 in ???

#10  0x408a60 in ???
#11  0xffffffffffffffff in ???

Please, could you help me to solve this error? Really appreciate any help on this.

These are my namelists. For these domains I use only one node.

I was able to solve the problem. For future reference and for anyone that might have this issue in the future, I'll leave here what I found.

The problem was that I was giving the max_dom parameter the wrong value. During my testing, I ran wrf.exe for my second domain on its own and I didn't realize that I had not changed the value of the parameter back to its correct value when running ndown.exe So, the issue was that I was running ndown.exe with max_dom = 1 instead of max_dom=3 (which is the number of domains I have).
