    <p>In a recent project we are currently getting 12031 errors. here is the complete error:</p> <blockquote> <p>Sys.WebForms.PageRequestManagerServerErrorException 12031 the status code returned from the server was 12031</p> </blockquote> <p>The problem is, this doesn't happen all the time and we are unable to reproduce the error on development environment. </p> <p>We use AJAX in our application and this exception happens on every page once in a while.</p> <p>I've found a post on SO with the same problem and tried changing <code>maxRequestLength</code> to "1" to see if I constantly get the same error but I don't. Instead, I'm getting </p> <pre><code>Maximum request length exceeded. </code></pre> <p>So I'm starting to think that it is not related to <code>maxRequestLength</code>. I'm actually out of ideas. I have a <code>ScriptManager</code> in my <code>MasterPage</code> and its <code>AsyncPostBackTimeout="240"</code>. That is the same amount of time (give or take). I get the 12031 error after 3,5 minutes of "nothing". I'm logging one of the pages and by logging, I mean logging every section of the page like "Page_Load is called" "xyz is called" etc and I have like 15 spots on the page for this. After user clicks a button and <code>ScriptManager</code> tries to do its job, no postback occurs, no logging happens. It is like the page wants to do a postback but too old to do it. Tries this for around 3,5 minutes and fails with the given error.</p> <p>Please, if you have any ideas, HELP ME OUT .</p> <p>Thank you</p>

    1. COError `12031` is `ERROR_INTERNET_CONNECTION_RESET`. It looks like an issue with the server or the network. Can you reproduce the problem if you open a session on the server itself and try from there?

    2. COYes I'm aware that it is ERROR_INTERNET_CONNECTION_RESET but I'm unable to reproduce it. The devices are actually kiosks and a web application is being called. I'm developing it on my PC and there is no problem on my side, it only happens in prod.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
