Re: [Discuss-gnuradio] Ettus B200 memory leak problem

[Derek Kozel]

Hello,

A memory growth issue was fixed at the end of last week. The fix commit is located here. If you build the UHD driver using the Maint branch I'd be very interested in hearing if your issue is fully resolved.

I'm using B200 SDR with Gnuradio 3.7.8 and uhd driver. I have compiled both Gnuradio and UHD from source. I'm using Intel atom processor with 1 GB RAM. Operating system is Lubuntu 15.04. I wrote a basic python program to observe this memory leak. I see memory consumption is increasing %1.4 per day. When i use cheap RTL sdr with osmocom driver, i haven't any leak problem but this B200 sdr with uhd driver induce this kind of memory leak. Has anybody had a similar memory leak problem? I attached my test program. this basic program only transports uhd samples to null sink.

best regards.

This is a known issue in current UHD, and it is being actively researched.  The cause isn't clear.
