WP_Options Table is full of itsec_ipcheck Rows

Probably, definately the transients that have expired.

To get a list of expired transients execute the SQL command below from phpMyAdmin:

select * from wp_options where option_name in (

SELECT replace( option_name, '_transient_timeout', '_transient' ) FROM wp_options WHERE option_name like '_transient_timeout_itsec_ipcheck_%' and option_value < unix_timestamp()

union

SELECT option_name FROM wp_options WHERE option_name like '_transient_timeout_itsec_ipcheck_%' and option_value < unix_timestamp()

)

To delete:

delete from wp_options where option_name in (

SELECT replace( option_name, '_transient_timeout', '_transient' ) FROM wp_options WHERE option_name like '_transient_timeout_itsec_ipcheck_%' and option_value < unix_timestamp()

union

SELECT option_name FROM wp_options WHERE option_name like '_transient_timeout_itsec_ipcheck_%' and option_value < unix_timestamp()

)

Do note that as of the WordPress 4.9.0 release the delete_expired_transients() core function was introduced. Probably best to use this WordPress core function 😉

It seems there is also a daily CRON job running named delete_expired_transients.
So certainly worth to verify whether CRON is functioning properly in your env.
