Hi,
I recently updated my Wiki from version 1.17 to 1.19. Since then, I have problems with the generation of the search index for MWSearch: very often and at random points after the Lucene build-script called dumpBackup.php, the database (mysql) 'stalls', the script stops with "A database error has occurred." and the wiki is not working anymore. I have to restart the mysql server to get the wiki running again.
Code: echo "Dumping $dbname..." cd $mediawiki && php maintenance/dumpBackup.php \ $dbname \ --conf $mediawiki/LocalSettings.php \ --aconf $mediawiki/AdminSettings.php \ --current \ --server=$slave > $dumpfile
All extensions (incl. MWSearch) are up-to-date, the Lucene scripts are updated, I updated the database after the upgrade (update.php) and the database is fine, no errors reported by the appropriate tools.
Running dumpBackup.php (without slave and conf) from the command line works fine.
Thanks for any help, Udo
