Minor: Engine Yard Gentoo 12.11 stack upgrade

December 19th, 2014

Action: You apply the following changes the next time you click the Upgrade button for your Engine Yard Gentoo 12.11 environment.

Note: For clarity, since we now have 2 Gentoo stacks, we refer to this stack as the Engine Yard Gentoo 12.11 stack. You can access it by using the Stack select field in the Environment UI:

It's best practice to upgrade your Engine Yard Gentoo 12.11 (stable-v4) stack regularly for the latest security and product updates. This week's updates:

  • Resolves issue seen in Chrome browsers (versions before 38) when encountering HTTP status code 408
  • Reduces the logging volume of stunnel to error level (previously debug level)
  • Enables process monitoring for bloated and orphaned workers for Passenger 4

    Note:

    • By default, the worker size is 250MB, though it can be changed by making a request to support.
    • As this monitoring is new for Passenger 4, it is more likely to find bloated or orphaned workers on its first use IF your app has been running a long time and prone to growing in size. This may result in a minor downtime while new workers are created to replace those terminated by the monitor.
    • You can first check if your workers are over this threshold using passenger-memory-stats command on each app instance (this includes app_master and solo instances), and if so, you can preemptively restart your app, select a low-traffic time to perform your upgrade, or open a support ticket to increase your worker size (only recommended if your app is always larger than 250MB but not constantly growing).

  • Bump MySQL 5.5 package to version 5.5.40
  • Bump MySQL 5.6 package to version 5.6.21
  • Backups and snapshots are now staggered, instead of occurring at the top of the hour they're scheduled to take place. They will occur at the same frequency, but may be done at a slightly different time. This helps Engine Yard to assure snapshots and backups all successfully occur without overloading our systems at the same time for all customers. You can see the time(s) your backups and snapshots occur by running sudo crontab -l on your instances.
