site_archiver@lists.apple.com Delivered-To: darwin-dev@lists.apple.com Hello, I'm working on a video player, and I have some issue with memory leak tracking. While the process is running, the 'real memory' and 'private memory' of the Activity monitor grow up slowly. I used a bunch of tool to track down what cause this issue (leaks, vmmap, heap, Instrument's ObjectAlloc) but I don't see any obvious leak. leaks does not reveal anything (no more than 20kB after 6 hours, so I think it safe to call it nothing). heap and ObjectAlloc's reports are stable too. The *All Allocations* line see not significant increase in memory usage. The only tools that report memory growth are vmmap and Activity Monitor. And from vmmap's reports I can see that the only region that significantly grow is IOKit region. Does IOKit has a special way to allocate memory that ObjectAlloc and heap are not able to track ? If yes, is there a way to track IOKit memory allocation specifically ? Or maybe this is an expected behavior and it's safe to ignore it ? Don't know if it's relevant, but I'm not playing the audio/video in the screen, but I'm using some SDI video card. -- Jean-Daniel _______________________________________________ Do not post admin requests to the list.
