Connection reset issue

Hi Team,

We have installed Orbeon Forms 3.8.201208142337 PE in one of our new production environments. In all the previous environments, it works just fine. But in this environment, we are continously getting "connection reset" issues.

We are not even able to open Form Runner's example forms like - orbeon/xforms-government/detail/DMV-14/. Error that we get is:

2013-06-12 12:29:07,341 INFO  SecurityFilter  - ********in do filter *********

We tried increasing tomcat memory and that helped a little (somewhat less number of errors), but we still see "connection reset" errors.

Any clues?

Thanks
Payal

Hi Payal,

Interesting. To figure this out could you set the logging to "development mode", per the section linked below. Then restart Tomcat, reload the page, and see if you find any interesting information in the orbeon.log. And of course, feel free to attach the log file to a response here.

Hello Payal,

Many of the examples use the xhtml doctype with the W3C uri,

http://www.w3.org/TR/html4/strict.dtd

When these pages are parsed, the parser reads the dtd and entity files
from the W3C site.  If it cannot connect, you may get this problem.

You could try WGET or similar utility from your server when you see
this problem.

Just a guess.

P.S. You can put local copies of the DTD and change the uri and doing
this can improve your performance.

Hi Payal,

From the log, it seems it can't load:

http://prod04.pearsonelt.com/orbeon/xforms-government/service/resources/DMV-14/en

I can access that resource from here, but maybe your network configuration doesn't allow for the URL to be loaded from the server itself? If that is the case, setting the oxf.url-rewriting.service.base-uri property should help you get around this.
