We are using the Onload software from AMD. Recently our application got an issue: zf_stack_alloc returns an ENOSPC error(out of PIO buffers).

• This application has already set “EF_PIO: 0” which means it does not use PIO buffer.
• However, some of our other applications on the same machine may have used some PIO buffer.
• My questions are:
• If I have already set my application to “EF_PIO: 0”, why the zf_stack_alloc function still returns ENOSPC error?
• Are we not allowed to call zf_stack_alloc when we do not have enough PIO buffer on a machine? Or there is some way to alloc the zf stack when we do not have enough PIO buffer: i.e. using TCPDirect without PIO? Thanks

Needed to google "Onload Software from AMD" to find out concerns Xilinx which was bought by AMD in the near past.
