What causes error 127 from table handler

Hi there, i got an error message got error 127 from table handler Last time i got that i lost a few rows in the affected table, but i thought that resulted from copying the db-files without shutting down the database, but the system i got the message from this time never had operations like this done on it, the tables belong to the same application, so what could i have done in php (PHP4.04 pl1) that introduced this error? The application does nothing fancy, just some basic operations. The tables have a few keys on them. the mysql versions are MySQL 3.23.32-log and MySQL 3.23.35-log no special features like transactions or so -- Grüße aus dem schönen Kleve Jens Kisters rosomm et partner Agentur für neue Medien GmbH Dienstleistungszentrum am Weißen Tor - Eingang B Gocher Landstrasse 2 47551 Kleve / Bedburg-Hau Telefon: 02821 - 97856-20 Telefax: 02821 - 97856-77 j.kisters@rosomm-partner.de http://www.rosomm-partner.de
