Can you provide some context under which this happens, i.e. does it
happen when you start gqrx or when you try to reconfigure the device?
In the latter case it is a known issue.

It happen when I press "Start DSP" button.

It's probably a problem with the device string. Assuming that you have up to date gr-osmosdr, try to remove the label, name and serial parts.

Thanks! It's work.
I set only 'addr=192.168.10.2' in "Device string"

Ok, sounds good. There may be other parameters that could be
necessary, see e.g. https://github.com/csete/gqrx/wiki/Device-strings
If you find other combinations that can be useful for your USRP /
daughterboard please let me know. It may be useful to put it in the
wiki for later reference.
