I was wondering if anyone could suggest tools and techniques for locating memory leaks in the kexts?

http://developer.apple.com/documentation/DeviceDrivers/Conceptual/WritingDev... has some good ideas. In 10.5.7: if you have a particular zone which is leaking, set the boot-args nvram variable with zlog={zone_name} and reboot, e.g. if the kalloc.512 zone is leaking, try sudo nvram boot-args="debug=0x144 zlog=kalloc.512" reboot, then reproduce. Use a second mac to attach, and use the findoldest, countpcs, and zstack macros to find the code which is leaking. See http://www.opensource.apple.com/source/xnu/xnu-1228.12.14/kgmacros for details. _______________________________________________ Do not post admin requests to the list. They will be ignored.
