Hi  
When I was running cctm in domain 2, I got this error.  
The model starts running with 1x26=26 cores.

I ran the core differently(1_10=10, 2_6=12, 4\*5=20 etc…) but the errors were all the same.  
I set CTM\_MAXSYNC 60 or CTM\_MAXSYNC 300 or CTM\_MAXSYNC 720, it didn’t run.  
And I turned off windblown dust in my run script.

I don’t know why I got the error.  
Someone could help me how can I do? Thanks in advance.
