Failed to map the DPM of a device

Check the application's restrictions
To allow mapping of the DPM to a user application, make sure the application is allowed to mmap enough memory (at least 64Kbyte).
You can check the current memory lock limit using the following command, which returns the maximum possible mapped memory in kB:
ulimit -l
