I was setting samp_rate to 1 msps and observed the same situation. In addition, in the example fosphor samp_rate = 56 msps and no errors occur.

If you replace the ZMQ blocks with NULL SINK blocks, do the overruns go away?

There’s no way the fpga to ARM channel can support those data rates.  Lower your sample rate to 5msps and try again.
