Can anyone give me some suggestions for this warning message. It appears when the report cost a long time to load data, as i described in page <a class='bbc_url' href='http://www.birt-exchange.org/forum/deploying-birt-reports-deployment-kit-iserver-express/16698-how-set-max-request-time.html'>http://www.birt-exchange.org/forum/deploying-birt-reports-deployment-kit-iserver-express/16698-how-set-max-request-time.html</a>.

Hi dianbo:

This warning usually means your system is too busy and it takes longer to send heartbeat message than usual. Failure to receive multiple heartbeat messages in row might cause the iserver to mistakenly restart related Java view server which could cause request failure.

To avoid that, you will need to properly configure your system so that it's not overloaded. For example, if a single machine is not enough to handle the load of your application, you might need to consider creating a cluster of two or more machines.
