[Discuss-gnuradio] Limitations of gr_block: max_possible_items_available = 8191

[luis]

Hello,

I created a block with a variable input rate, but when I run the flowgraph I get the following error:

sched: <gr_block galileo_e1_dll_pll_tracking_cc (46)> is requesting more input data
  than we can provide.
  ninput_items_required = 16000
  max_possible_items_available = 8191
  If this is a filter, consider reducing the number of taps.

If I don't exceed the limit of 8191 items the block works correctly but I need to exceed this limit for the experiments I'm doing.

Is this a limitation of gr_block? Is there any way to exceed this limit?

In the other way I tried to use gr_sync_decimator but does not work because sometimes I need to consume 16000 ninput_items, sometimes 15999, and so on, and gr_sync_decimator seems to have a fixed rate.

Thank you in advance. Best regards.

Luis
