Too many SQL query

Hello,
My server is having experience heavy CPU load by mysql. After I checked current running query there are multiple query related to wordpress database. The query as follows :
SELECT session_key, session_value FROM wp_64395b34e1_woocommerce_sessions WHERE session_value LIKE

Even when I kill the process, a new query with the exact same query pops up. What cause this and how can I prevent this?
