16GB of RAM
App runs inside docker: Docker version 17.03.1-ce, build c6d412e

2. Memory usage problem
I am having memory usage problems in production, where things do fail
because some Go processes use much more memory than expected.
I have prepared a test, where I am running my my server application, and I
am measuring, how memory is consumed for one process.
I fount out that more and more system memory is consumed with time. On the
graph below, you can see how RSS has risen from ~0.5GB up to ~6Gb in a few
days.

The app does a lot of image processing for the images from remote source
(in the range of 100 images each second). All this processing, means a lot
of allocations, so naturally I tough, this must be memory a memory leak.
So I run pprof (see attachment: pprof.log), which reports heap usage below
300Mb. This heap usage, doesn't seam to change much over the time.
Then, there are some CGO bindings with OpenCV, so I thought there must be
some leak in C code. I run the thing with Valgrind, which didn't find
anything except some minor leak, which I had already fixed by now.
<https://lh3.googleusercontent.com/-rQzo0h1nFmc/WQxWfRtgdaI/AAAAAAAAAEw/fyQ4N86p2csv0ktKCb5xaIB00hNSBrgagCLcB/s1600/rss.png>
I also run the app with GOGC=50, but it didn't help.
I am looking for the explanation what is happening, and how this can be
solved?
Thanks!
