I'm trying to playblast some long sequences, and my computer is using more and more memory to churn out the playblast. I'm not even playblasting to ip or mplay, I'm writing the images straight to disk. When I cancel the playblast, the memory still remains used up, until I close the houdini session. The cache manager under the windows tab didn't help me. How can I release the cache as I playblast, because at the moment, I need to re-open my houdini session every 500 frames to release the cache.

Thanks!

Suspecting this is a memory leak issue..
