Hi, our system administrators recently upgraded the version of MySQL
they are running and one of the wikis I run has begun failing. I have
another MediaWiki running 1.4.x and it doesn't seem to have any
problems, but my wiki running 1.5.2 began failing reporting messages
like "Error in fetchObject(): MySQL server has gone away". I tried
installing a newer version of PHP (5.1.6), which didn't work. I also
tried upgrading to MediaWiki 1.7.1, which seems to be working a little
better, but it fails before it writes the LocalSettings.php file.
Does anyone have any ideas of what to try next?
Alternately is there a tool that I could use to do dump all the wiki
pages to something vaguely like the MediaWiki markup such that I could
just start over completely from scratch if needed?
