How can I solve this?

Answer 1

Make a dump from you database: Step 1: On you ssh shell do this command:

mysqldump -h databasehost -u user -pPASSWORD databasename > filename.sql

Step 2: So you can try:

TRUNCATE core_url_rewrite;

And try reindex again.

This should do the trick.

Answer 2

Do not truncate: core_url_rewrite

This is the worst advice ever, you will lose all customized SEO urls! Just dont do it!

What worked for me was SSH and running:

php -f ./shell/indexer.php -- -reindex catalog_url

If nothing else works then maybe attempt the table dropping idea, but only as a last resort!

Answer 3

I'm not certain why your truncate is getting interrupted, that's problematic. You can try rebuilding the index from the shell script from the main Magento directory:

php -f ./shell/indexer.php -- -reindex catalog_url
