Lazy administration led to "server meltdown."
I admit: I don’t pay attention to my Linux servers like I should. They have lulled me into a false sense of security due to their stability. This morning, though, my monitoring app sent an email to me. A snippet:
The VM XXXXXX has exceeded the notification threshold (90) for CPU Usage by averaging 90.8% for the last 2 hours.
mysqld sitting at 87%. Um, ok…
: sudo mysqladmin shutdown
Wow. Reboot. All is well.
Yep, mysqld choked on the leap second.
Stupid leap second. Stupid mysql.
Time to switch to SQL Server Azure.
