Issue Description

https://github.com/IntelRealSense/librealsense/blob/master/doc/d435i.md
Processing IMU sensor data according to the above, process memory (Private Bytes) has increase about 27KB/sec.
Leave it running 36 hours, memory usage keep increased and process has died.
Strangely, I got same result by more simple code.

#include <librealsense2/rs.hpp>

int main()
{
    rs2::config cfg;
    cfg.enable_stream(RS2_STREAM_GYRO);
    cfg.enable_stream(RS2_STREAM_ACCEL);

    rs2::pipeline pipe;
    pipe.start(cfg);
    getchar();
}

This looks like a memory leak to me. Is there a suspected cause?

@terranas hello, thank you for the report.
Seem like a possible bug. We'll look into this

I am having a similar issue using the Intel D415.

Just so we are on the same page I used the code example provided by terranas and evaluated it with Valgrind.

I've met the same problem. Have you got any solution?

Hi all, we have also experienced similar issues running the same setup @JamesPiggott used. We have also tested on Ubuntu 16.04 which gave similar results.

Also, the valgrind report @JamesPiggott attached is similar to the one in #3433.

Downgrading to SDK 2.17.1, a version we previously used, gives no memory leak.

This seems to be affecting us as well. Any updates? We are on 2.19.1 but are happy to update to one where it's fixed

@terranas This issue was fixed in the current SDK release. Could you please give it a try?
