This may be timing-out due to performance issues on your host, or it may
be a bug in your code.
Have you tried using the the rx_multi_samples example at the same sample
rates?
2 x 50Msps is a lot of data, and with the short "packets" on PCIe, your
computer will be working fairly hard at servicing those samples.
Before we get in to debugging your code, could you:
(A) Try lower sample rates
(B) Try rx_multi_samples
