Sounds like MySQL crashed... report bug to mysql or try a different system?
Error at line 130: # mysql -u root -p wikidb < tables.sql Enter password: ERROR 2013 (HY000) at line 130: Lost connection to MySQL server during query mysql> CREATE UNIQUE INDEX /*i*/user_name ON /*_*/user (user_name); ERROR 2013 (HY000): Lost connection to MySQL server during query It’s bug with MySQL, not MediaWiki?
Your log extracts are showing that MySQL is crashing and restarting; this is consistent with the output you show most recently (server connection going away). If MySQL is crashing, it's either a bug in MySQL, a bug in the compiler or libraries used to build and run MySQL, or a hardware bug in the computer that causes a software failure. There is nothing in the SQL statements we're pushing that *should* be able to cause a crash, unless the above are true.
