Troubleshooting

This problem particularly occurs when the views is upgraded to 3.x in Drupal 6. The nodereference field which gets list data from a view returns only 10 results irrespective of whatever is set on the views page.

There is an easy solution to alter by modifying the items_set_per_page using views hooks.

Search for drupal_set_time_limit in Drupal directory and modify the line as below. Ensure that it is restored later once the required operation is over:
For example: Modify the following line in locale.inc file in includes/locale.inc.

<?php
drupal_set_time_limit(240); 
?>

and set to 1800.
