504 errors when loading multiple copies of a gadget on a page?
I am encountering an issue where loading multiple copies of the same gadget
on a page results in 504 errors. I am using the latest 2.5 Shindig. My
test involves 10 copies of the gadget:
<?xml version="1.0" encoding="UTF-8"?>
<Module>
<ModulePrefs title="Home" >
<Require feature="opensocial" version="2.5" />
<Require feature="dynamic-height" />
<Require feature="views" />
</ModulePrefs>
<Content type="html" view="home, default">
<![CDATA[
<div>Go Go Gadget.... </div>
]]>
</Content>
</Module>
I am using gadget rendering code similar to the Shindig examples
under /Container (createGadget, addGadget, renderGadget). Some of the
gadgets render correctly, the others come back with a
Unable to retrieve spec for http://XXX/testGadget.xml. HTTP error 504
and the error is
NetworkError: 504 Gateway Timeout -
http://XXX/shindig/gadgets/ifr?container=default&mid=5&nocache=1&country=ALL&lang=ALL&view=default&parent=http%3A%2F%2FXXX%3A9080%2Ftestcre%2Ften-gadgets.html%3A%2F%2FXXX%3A9080&st=john.doe:john.doe:appid:cont:url:0:default&url=http%3A%2F%2FXXX%3A9080%2Ftestcre%2FtestGadget.xml#rpctoken=75940654
Any ideas?

Interesting thing is it resolves some instances. In the scenario Chris
tested I saw 10 instances of the same gadget with Shindig and the simple
gadget.xml file on the same server. Atleast 5 of them displays well and
other 5 come back with 504 errors. We tried another proxy by increasing max
host connections but didn't help.
Wondering if there a way to bypass the proxy completely since gadget is on
the same server?

Hi Chris,
Making sure you server can resolve its own hostname would be another thing
to check.
You can also turn on FINEST logging for org.apache.shindig in your
webserver to see if anything useful appears in those logs.
Best regards,

Actually, they are on the same server! I don't see any error logs besides
the 504.

504 error usually happen when there is a problem with HTTP connection from
one server (in this case your Shindig server) to the target server (which
is the endpoint where your gadget.xml is hosted.)
Could you check access logs in your gadget.xml server to see if there any
error logged?

504 error usually happen when there is a problem with HTTP connection from
one server (in this case your Shindig server) to the target server (which
is the endpoint where your gadget.xml is hosted.)
Could you check access logs in your gadget.xml server to see if there any
error logged?
