There is this very strange issue on the production server for only one content type that the breadcrumbs and node data do not render in the node view page.
But when we clear cache it shows the data for the node but when we refresh the page again then the data for that node is removed again. We have added some custom node variable using the hook_node_view those are also not visible. We have the same configuration of production server on the staging server where this is working fine. The code below is adding variable in the node view which is working fine every where except the production server.
PHP - 5.3.17
/*
* Implementation of hook_node_view
*/
function mmt_flight_schedule_node_view($node, $view_mode, $langcode)
{
// p($node);
if($view_mode == 'full' && $node->type == 'flight_schedule_node')
{ //p($node);
//get the template configuration saved for this page number from city template node
$template_data = _mmt_common_get_template_data('flight_schedule_template');
//set the meta information in node
$token_data = array();
$token_data = _mmt_common_get_token_data($node, $template_data);
_mmt_common_set_meta_fields($template_data, $node, $token_data);
//set the seo head information in node
_mmt_common_set_seo_information($template_data, $node, $token_data);
