Problem when running DMA_AFU on ASE simulation.

I am using 1.1 production version and using DMA_AFU from sample to build ASE simulation.

From the simluation script, I can invoke the simulation, the log file is:

[SIM] Simulator started...

# [SIM] +CONFIG /home/xxxxx/intel/dma_afu/build_sim/ase.cfg file found !

# [SIM] +SCRIPT /home/xxxxx/intel/dma_afu/build_sim/ase_regress.sh file found !

# [SIM] tcsh/csh | setenv ASE_WORKDIR /home/xxxxx/intel/dma_afu/build_sim/work

# [SIM] For any other $SHELL, consult your Linux administrator

# [SIM]

# [SIM] Ready for simulation...

# [SIM] Press CTRL-C to close simulator...

# [SIM] Session requested by PID = 82796

However, from the sample sw side, when I executed the application

I got the following error:

[APP] ASE Session Directory located at =>

[APP] /home/xxxxx/intel/dma_afu/build_sim/work

[APP] ASE found a stale Application lock with PID = 82096 -- this will be removed

----------------------------------------------------------------

The syntax I run the application is :

sudo LD_LIBRARY_PATH=$PWD ASE_WORKDIR=/home/xxxxx/intel/dma_afu/build_sim/work : ./fpga_dma_test 1

Can anyone tell me how to fix the problem?

Thanks a lot.
