I'm trying to use my rpi as sdr server, all works perfect, but i'm stucked with one problem:
I'm using SDRSharp via RTL-SDR/TCP to listen, and when i connecting to rpi first time - all perfect, disconnecting also.
But on second connect (not 2 connects at once) my waterfall on sdr# hanged, like no data.
After disconnect there is two variants on rpi server console:
1. 100% cpu load and hanged process (can kill only with sigkill from other session) (code example 1)
2. Segmentation fault error and closed process, need to restart rtl_tcp.
Looks like that Chinese guy have same problem. But it wont work for me. Looks like article too old for new versions.
And this one too.
