Are you running on a 32 bits architecture ? I have seen case where 1.7G is way too much for the total space mysql is allowed to use, especially if you have innodb buffer set to bigger than default value(8MB). Also you should check that the user is really allowed that size (ulimit).
The duplicate for key is most certainly due to the crashing of mysql in the middle of the update of the key... Could it be different query on that server that makes it crashed ? Sorry don't know what to suggest really, it must be a real pain :( Regards Math aka ROunofF On Sat, Sep 08, 2007 at 06:30:08PM -0400, Matt Juszczak wrote: > Hi all, > > We've been having our master database server continually crash about once > or twice per week.
