[quote="clalancette, post:2, topic:3261"] I ran `valgrind --leak-check=full ./build_isolated/intra_process_demo/image_pipeline_with_two_image_view`. Looking at the output from that, it looks like the leaks are coming from somewhere down in the OpenCV code. [/quote] The leaked memory from within `cvCreateMat` is constant - two times (one per window) independent how long the process is running. So this is not responsible for the increasing memory reported. --- [Visit Topic](https://discourse.ros.org/t/increasing-memory-usage-for-publishing-nodes-with-enabled-intra-process-communication/3261/7) or reply to this email to respond.
