Comment (by dingdang):

 WP Version: 4.8.1

 Probably caused by: https://wordpress.org/plugins/wp-statistics/ (latest
 version)

 - Had 500K records in its table, causing (overloading and) process
 terminations by the web server:
 PHP Fatal error:  Maximum execution time of 30 seconds exceeded

 - PHP running as CGI

 - generated 120GB of error_log, repeating the following 3 lines

 PHP Warning:  next() expects parameter 1 to be array, null given in
 .../wp-includes/class-wp-hook.php on line 303, referer: .../wp-
 admin/index.php
 PHP Warning:  current() expects parameter 1 to be array, null given in
 .../wp-includes/class-wp-hook.php on line 287, referer: .../wp-

 PHP Warning:  Invalid argument supplied for foreach() in .../wp-includes
