Why is the "ci_sessions" table type MyISAM?

[eluser]Référencement Google[/eluser]
InnoDB takes his power while there is relational things in the DB, but is slower than MyIsam engine, you don't need relations for session stuff, don't you?

Storing session data would be even better to do with the Memory engine, but it won't accept the CI text field used for datas, so your best choice is to keep it as MyIsam.
