Change the HTTP transport settings for dmgr:

    Port 9090 is the default HTTP Transport port for the administrative console. If security is enabled, click on the SSL-enabled secured port.

  2. On the Custom Properties page, click New.

  3. On the settings page for a property, specify the transport property name and the value.

  4. Specify a name of MaxKeepAliveConnections and a value 0.

  5. Click OK.

  6. To change the I/O timeout to 60, use ConnectionIOTimeOut as the name.

  7. To change the keep alive timeout to 60, use ConnectionKeepAliveTimeout as the name.

  8. Click Save on the console taskbar and save the changes to the configuration.

  9. Restart the dmgr server.
