_MALLOC calls are getting failed some time after my application is started. I tried with OSMalloc as well , its also failing. In which cases _MALLOC Fails ? .

_MALLOC will often fail if you pass M_NOWAIT. M_WAITOK is reliable. I've never encountered problems using M_WAITOK.

Once my application is started ( kext as well ) , the system hangs on PowerBook G4 , But on iMac G5 its works without any problem.

If it hangs, you might be caught in a loop or something in your kext. Set up two machine debugging and break during the hang. You will probably be able to get some useful information about it. <http://developer.apple.com/documentation/Darwin/Conceptual/KernelProgrammin g/build/chapter_18_section_5.html> Eric _______________________________________________ Do not post admin requests to the list.
