This morning, at 8:32 AM, one of our customer MySQL servers crashed due to an apparent bug in MySQL. Additionally, after the crash it was failing to restart. The trouble was isolated to a specific user’s database, which when manually removed, allowed the MySQL server to start normally. The server appears to be functioning correctly at this time.
Was it non ANSI/UTF character related?
We don’t know what lead to the initial crash but we know that a group of Berekely Database format tables were preventing it from starting properly.
