OK so it is more now I have read again your first and second post, related to the MySQL engine: Do you have a MyISAM engine running too?
What most admins I work with don't understand is the recommendations often given by vendors on tuning their soft are based on standard configurations and don't really apply when out of that.
What you see to me is the backside effect of big SGA that could be more efficient when size is reduced since the SAN bays have huge cache too... Either it is loosing its time parsing the storage now nearly full either the storage is too fragmented

NAME
Dancer::Session::YAML - YAML-file-based session backend for Dancer DESCRIPTION
This module implements a session engine based on YAML files. Session are stored in a session_dir as YAML files. The idea behind this module was to provide a transparent session storage for the developer. This backend is intended to be used in development environments, when looking inside a session can be useful. It's not recommended to use this session engine in production environments. CONFIGURATION
The setting session should be set to "YAML" in order to use this session engine in a Dancer application. Files will be stored to the value of the setting "session_dir", whose default value is "appdir/sessions". Here is an example configuration that use this session engine and stores session files in /tmp/dancer-sessions session: "YAML" session_dir: "/tmp/dancer-sessions" METHODS
reset to avoid checking if the sessions directory exists everytime a new session is created, this module maintains a cache of session directories it has already created. "reset" wipes this cache out, forcing a test for existence of the sessions directory next time a session is created. It takes no argument. This is particulary useful if you want to remove the sessions directory on the system where your app is running, but you want this session engine to continue to work without having to restart your application. DEPENDENCY
This module depends on YAML. AUTHOR
This module has been written by Alexis Sukrieh, see the AUTHORS file for details. SEE ALSO
