There seems to be a memory leak in the jt9 process started by wsjtx. I have included a chart showing the memory use growing from about 20MiB to over 300MiB in the course of 11 hours. I set wsjtx to monitor 40m overnight and recorded the memory stats produced by /proc/*/statm at one minute intervals. The change in slope of the curves indicates the band opening and more signals being decoded.

The configuration here is Ubuntu 17.10 with an RTL-SDR. gqrx demodulates USB, filters and feeds the audio to wsjt-x 1.9.0-rc1 using pulseaudio.

Just checking in. Have you figured out why your build of the executable "jt9" shows a significant memory leak, but ours does not?
