ps_to_http results in "ERROR: request failed"

[hoyleb]

Hi all,
I've been trying to follow the tutorial found here: http://micha.gd/realtimestream/ .
I am using libevent-1.4.14 . I get to the point in the tutorial where I issue this command:

%> ps_to_http --destination-get-url="http://127.0.0.1:8081/put?data=%s" --pubsub-url="http://127.0.0.1:8080/sub?multipart=0"

It works fine for a few minutes [pub/ sub/ requests ] but the it dies with this error:

ERROR: request failed

Any ideas what I might be doing wrong?
