I'm trying to verify the 58000 links I have in my database but it still doesn't want to work :(

I've tryed in the admin window and after a few succeeded checks I got this :

A fatal error has occured:

Invalid query string '' at /home/kestu/cgi-bin/links/admin/Links/Tools.pm line 328 - Missing URL - Request Failed (unresolvable)
Checked

Please enable debugging in setup for more details.

- Missing URL - Request Failed (unresolvable)
Checked

After this message an other one :

k Trace - Missing URL - Request Failed (unresolvable)

Checked 15 - http://www.atelier-artimage.com - Success (200). Message: OK 200

and so on :(

I've also tryed in SSH, but there were a lot of errors too :

GT::SQL::Table (5063): Status cannot contain the value '[undefined]' at nph-verify.cgi line 440.
GT::SQL::Table (5063): Status cannot contain the value '[undefined]' at nph-verify.cgi line 446.


and :

GT::SQL::Table (5061): Failed to execute query: 'SELECT * FROM lsql_Links WHERE (ID = ?)' Reason: MySQL server has gone away at /home/kestu/cgi-bin/links/admin/GT/SQL/Driver/MYSQL.pm line 121.
