Hi Nitin,
You might get problems with max spout pending if you delay acking of one
message until another arrives. In this case having a low max spout pending can
cause the buffers to fill before the awaited message arrives. But this type of

Hi Nitin,
Though it decreases throughput when max spout pending value is small, it should

if you don't

Btw, your spout latency is a bit high (10s).
