DOCA Comch execution error

Hi, I have tried to execute DMA Copy application on my BF2 following application guide, but faced error below.
There are two libraries leveraged in the application, DMA and Comch. I also tried to execute each sample of the libraries, and faced the same error with Comch sample (DMA sample works well). How can I fix it?

DOCA version on BF2:
DOCA SDK Version (Compilation): 2.8.0081
DOCA Runtime Version (Runtime): 2.8.0081

DOCA version on host:
DOCA SDK Version (Compilation): 2.8.0082
DOCA Runtime Version (Runtime): 2.8.0082

Output on BF2:
