64MP USB Camera locks up - possibly overheats


I have your 64MP USB 3 camera and I am experiencing the following problem.

I have setup a test whereby the camera takes a 64MP picture once a minute. The camera works fine for a few days but if I stop my program and restart it the camera will not take a picture but just hangs.

I have noticed that the longer I leave the camera on the worse the problem gets.

Could this be a possible overheat situation ?

At the moment I have the camera on my desk, not in a case but as supplied by yourselves. There is no external cooling being provided eg. a fan.

Does the camera module need cooling in order to work reliably ?
