Hey Nikos,\
\
Sorry to here that you were not successful.\
\
Just for your information, I did just recently(this week) fix a bug that might 
be related to your issue, that should be part of the upcoming UHD release 4.9.\
\
The bug that was fixed is related to a scenario, where if you use the 
\`NUM_SAMPS_AND_DONE\` mode for RX streaming, if you are slow in receiving the 
data on the host, and there is an Overrun(the “O”) on the FPGA side, after the 
overrun has occured if you try to recv() the rest of the data, the remaining 
data would have been lost.\
\
This sounds very similar to the problem you are facing, at least if you are 
using one of the standard bitfiles that includes the DDC block in your RX 
datapath.\
\
The fix should be available on the UHD master branch soon, probably end of the 
week or next week, or you can wait either for UHD  version 4.9 RC2 for testing 
if this fixes your issues,  or wait until the regular version 4.9 release 
occurs.\
\
The fix is on the FPGA side, so if you can not wait, and want to add the 
potential fix to build your own bitfile let me know, and I can provide you with 
more details.\
\
Regards,\
Niels
