USRP X300 error: Dirty: RxStreamer#1[INPUT_EDGE:0 atomic_item_size]

[NIDHIPANDA]

Hello,

I am having USRP X300 device with following tool versions:

Vivado 2021.1 - AR76780n,
GNU radio version - v3.11.0.0git-820-g2adbd4ea
UHD version - UHD_4.7.0.0-84-gbdada1ed

I have added FFT and Spliter RFNoC blocks in my bit file. The "uhd_usrp_probe" command shows correct connection in the blocks.

| | RFNoC blocks on this device:
| |
| | * 0/DDC#0
| | * 0/FFT#0
| | * 0/Radio#0
| | * 0/Replay#0
| | * 0/SplitStream#0

| | * 0/Replay#0:1==>0/SEP#4:0

However, on running example code available on GNU RADIO "rfnoc_split_stream.grc". I get following error:
_Please run: sudo sysctl -w net.core.wmem_max=2453333
[WARNING] [0/Radio#0] Attempting to set tick rate to 0. Skipping.
[ERROR] [RFNOC::GRAPH::DETAIL] The following properties could not be resolved:

I tried by changing FFT size to 256 and also SPP same for all blocks. but I get same error. Please help me to resolve this issue.
