Transaction aborted: timeout error in Salesforce

By | January 14, 2014

In one of our projects in, we have been using the JS remote action calls many a time for custom reporting purpose. While testing, sometimes we face an issue and the error message displayed is “Unable to connect to the server (transaction aborted: timeout)”. This error occurs randomly and only sometimes.

We are not sure if these errors occur for a number of concurrences in javascript remoting calls. They appear to be specific connection errors. It seems that sometimes, the JS remote action calls take more than 30000 milliseconds which is the default timeout value for JSRemoting method.

For this reason, we had set the parameter timeout value to other some other value than the default value i.e. 120000 milliseconds as shown below –

{buffer: true, escape: true, timeout: 120000}

The other way to do this will be to set this value at the page level as shown below –

<script type=”text/javascript”>

Visualforce.remoting.timeout = 120000; // Set timeout at page level


This seems to have solved our Transaction aborted: timeout message issue.
