Hi,
unfortunatly, I have only limited access to log files. I can only find a PHP Fatal error: Call to a member function isDisabled() on a non-object in xyz/includes/db/DatabaseError.php on line 231 (not sure, whether taht is result of me restarting mysql) and dumpBackup.php shows: A database error has occurred.
That is a call to $wgOut->isDisabled(). Seems $wgOut wasn't set at that point.
Query: SELECT page_id,page_len,page_is_redirect,page_latest FROM `page` WHERE page_namespace = '0' AND page_title = 'E15' LIMIT 1 Function: LinkCache::addLinkObj
That sentence should be perfectly fine. Don't you have an error code and/or description? (such as 'server timeout')
Of course, I did run update.php (a few times).
Most SQL errors are due to having an old database schema (thus the suggestion of update.php), but it's not your case.
Well, when Lucene/dumpBackup stalls, the mysql server obviously is not out completely; a forum and another wiki on the same server still work fine. Just the wiki with MWSearch does not work at all and I have to restart mysql to get it working again.
I suspect there is some deadlock there. Can you please run SHOW PROCESSLIST to the database when it doesn't answer to the wiki?
