Today I've installed QO100_Transceiver V1.70 on an Ubuntu 20.04 desktop machine using the provided install script. Mono is having a huge memory leak and after a minute or so the machine crashes due to memory being exhausted. Mono starts with about 700 MB of memory footprint. One minute later, the footprint reaches 3 GB. The issue seems to be related to the spectrum graphics. If I disable the feeding of rxdata from PlutoSDR to the FFT FIFO in trxdriver, the problem stops. But, of course, no spectrum graphics.
Is anyone else having this issue?
