English Wikipedia Special:AbuseFilter is reporting:
A database query error has occurred. This may indicate a bug in the software.
Function: IndexPager::buildQueryInfo (AbuseFilterPager) Error: 2013 Lost connection to MySQL server during query (10.64.48.28)
According to ops, the query seems to simply take too long, so the special page will have to be smarter with it's queries ?
Edit: [this happens on all wikipedias, with a large enough abuse filter log]
