I have a site that was upgraded from Drupal 6 to Drupal 7. This site is quite large and has over 22,000 nodes.
When we try to run a bulk update of aliases, we get the following error:
An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /batch?id=1000170&op=do StatusText: Internal Server Error ResponseText: 500 Internal Server Error Internal Server Error The server encountered an internal error or misconfiguration and was unable to complete your request.
In addition to the previous error every time we found with phpMyAdmin the following SQL query hanging on the server for long time:
SELECT COUNT( * ) AS expression
SELECT 1 AS expression
FROM users u
LEFT OUTER JOIN url_ali
...and this other query:
Copying to tmp table
SELECT n.nid AS nid
LEFT OUTER JOIN url_alias ua ON CONCAT('node/', n.nid) = ua.s
It seems like these queries take too long and AJAX gives up after a while.
When running the bulk update for Taxonomy terms only (about 250 terms), it works very well.
Thanks for this great module. One of my favorites.
