Copied and pasted some code to reproduce the issue. Hopefully it makes some sense... receiverLoop1 is increasing mem usage, receiverLoop2 does not.
Btw, set_rx_iq_balance function seems to be inverted, setting it to false on the E310 reduces spectrum images more than 50 dB, while true reduces only about 24 dB... https://nor01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fdrive.google.com%2Ffile%2Fd%2F1cMLXzNLpkkhBQ9gtFgeZgm-8N3v-OEFd%2Fview%3Fusp%3Ddrivesdk&data=04%7C01%7Cjsk%40nkom.no%7Cf5e97e128b734e566f5308d9aeb928b6%7Cad83e65c03f64cfdb79947a2fafd7bce%7C0%7C0%7C637732932540044724%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000&sdata=d4z5DA9RGIP1MSe1JCD9njDShyl7o19JAP8lXtl3Op0%3D&reserved=0 ________________________________ Fra: Jonathon Pendlum <jonathon.pend...@ettus.com> Sendt: tirsdag 23. november 2021, 19:23 Til: Marcus D Leech Kopi: Skorstad, Jørn; usrp-users@lists.ettus.com Emne: Re: [USRP-users] Re: UHD 4.1 memory leak?

I am using RFNOC blocks RADIO and DDC, and setting up an RX stream using graph->create_rx_streamer. The receiver loop is running in its own thread doing something like this (simplified): uhd::stream_cmd_t stream_cmd(uhd::stream_cmd_t::STREAM_MODE_NUM_SAMPS_AND_MORE); stream_cmd.num_samps = size_t(sampsPerBuff); stream_cmd.stream_now = true; stream_cmd.time_spec = uhd::time_spec_t(); for (;;) { rx_stream->issue_stream_cmd(stream_cmd); rx_stream->recv(&buffer.front(), sampsPerBuff, md, 3.0, false); std::this_thread::sleep_for(std::chrono::milliseconds(2)); } I am developing for an E310 sg3. When calling issue_stream_cmd repeatedly this way memory usage goes up until resources are depleted (few hours). If stream_cmd is replaced with STREAM_MODE_START_CONTINUOUS and called just once memory usage is normal. But for the application developed the mode NUM_SAMPS_AND_MORE is better suited. It is also what we used with the 3.14.1 library, without any memory problems like this. Any tips?
