Great tip on finding transaction bottlenecks in MySQL

On the MySQL performance blog there was a great article posted two days ago on how to debug long-running transactions in MySQL.

Long-running transactions are transactions that are left open and not committing or reverting. Maybe because of a failed/halting application or just an application that is taking long to process.

The article goes into details about the problem and they also share a little bash script you can use to capture these long running transactions.
