Hi Wu, There really isn't enough information for others to know what might be amiss, The only code you provide is how you create a single Camera, you don't provide any information about how you use this, what type of point the camera is.
The only things I can suggest is to look at the memory tracking tool you are looking at, it may well be giving you false positives. Robert.
