Hi Sumit - Do you have your GR OOT in a public repo where we could
review all of the code & try the example ourselves? That's the most
reliable way to handle such potentially in-depth queries such as yours.
As a quick reply without knowing more specifics, are you using the
"hier_block2" for the base class for your main block? If so, then you
can't do signal processing within this block; all a "hier_block2" block
is good for is encapsulating other blocks, connecting them internally as
well as to the "hier_block2"s input(s) and output(s); no "work" here!
>From the debug printout, likely candidates for this issue would be the
block "fft_vxx" or "ieee802_11_soft_frame_equalizer_dc".
Hope this is useful! - MLD
