    I have noticed that tons of cron jobs named in timestamp are added into wp_options tables every time I refresh the page. it looks like the following:

    Hook Name Arguments Next Run Recurrence
    1440864546 None 1970-01-01 00:00:00 (now) Non-repeating
    1440864611 None 1970-01-01 00:00:00 (now) Non-repeating
    1440864630 None 1970-01-01 00:00:00 (now) Non-repeating
    1440864631 None 1970-01-01 00:00:00 (now) Non-repeating
    1440864692 None 1970-01-01 00:00:00 (now) Non-repeating
    1440864710 None 1970-01-01 00:00:00 (now) Non-repeating
    ….. there are much more just after few refresh..

    and they are added by update_options in the core
    update_option()-
    _set_cron_array()
    wp_schedule_single_event()
    _wp_check_for_scheduled_split_terms()
    do_action(‘admin_init’)

    any idea?

    WordPress 4.3 accidentally contained a minor bug relating to term-splitting, which in some rare cases, can cause a large number of wp-cron jobs to build up which will never actually complete. This issue is already fixed, and the issue will be solved by WordPress 4.3.1.

    However, until that is ready, you can fix the problem yourself by following these instructions. Be sure to follow the instructions carefully and in the order that they are given:

    here is part of option_value with option_name ‘cron’ in wp_options table, it seems just to keep repeating some thing..
