Storm Netty connection problem

Hi all,

I'm trying to run a Storm topology and I'm getting the following errors 
in my bolts logs:

I understand that at the end the connection has been re-established. 
However, is it normal to get these errors? Does this mean that there is 
a network error which is not related to Storm?

Thanks in advance,
Dimitris Sarlis

As far as I know, if a worker comes up before another downstream worker
that it is trying to send tuples to, you will see messages like
that....also if a downstream worker dies and has to restart you may see
this.

Same here, I'm guessing it's some benign race condition.
There was some code change around this area for reducing the amount of
ERROR logs, so in future releases you should at least see less ERROR logs.

Hello Dimitri,

I also get similar errors on my AWS cluster and I have not figured out how
to resolve them. However, I do not think that they necessarily affect your
topologies.

Nikos
