I have an application which trades lots of small data packets with the DSP. It currently works fine using memory mapped DSP access, but I would like to try message based access since I'm told memory mapped will not be supported in the future. The application trades a few hundred messages back and forth with the DSP, and then snddriver_dsp_read() gets a KERN_RESOURCE_SHORTAGE error, and the system promptly reboots with a 'zone "messages" empty' error. This sounds to me like the OS has a core leak. Any suggestions (besides giving up on MACH and sticking with the memory mapped mode)? Please reply via email. rwb@vi.ri.cmu.edu
