This is similar to the issue #9565 .
I'm using version 3.04, and I get the following error when importing logs with import_logs.py.
2017/05/19 22:01:37 [error] 7#7: *25796 FastCGI sent in stderr: "PHP message: Error in Piwik (tracker): Error query: SQLSTATE[22003]: Numeric value out of range: 1264 Out of range value for column 'visit_total_interactions' at row 1 In query: UPDATE piwik_log_visit SET idvisitor = ?, user_id = ?, visit_last_action_time = ?, visit_exit_idaction_url = ?, visit_total_actions = visit_total_actions + 1 , visit_total_interactions = visit_total_interactions + 1 , visit_total_time = ?

This can be fixed by changing https://github.com/piwik/piwik/blob/3.x-dev/plugins/Actions/Columns/VisitTotalInteractions.php#L20 to protected $columnType = 'INT(11) UNSIGNED DEFAULT 0';
Another field visit_total_searches may also need to be changed.
