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.
