 Priority:  normal        |   Milestone:  Unassigned                      
Component:  General       |     Version:  2.9                             
 Severity:  critical      |    Keywords:  suspension, excessive cpu cycles
--------------------------+-------------------------------------------------
 Users are suddenly finding their accounts suspended because of excessive
 CPU cycles. However after investigating it appears the web hosting
 companies are properly configured and no hacks have occured. It seems that
 wp-cron is looping and consuming huge amounts of cpu cycles.

 '''Versions:'''
 This occurs across the past several versions on fully updated versions.

 '''The effect:'''
 Excessive CPU cycles with resulting suspension of a users account.

 '''Plugins and Theme:'''
 I detect no relationship to plugins and themes. I am presently running
 only 8 plugins.

 '''Frequency:'''
 Sadly, this is an intermittent issue. But a check of the Wordpress.org
 forum will show regular questions about this problem.

 '''Server Environment:'''
 Host is [http://www.inmotionhosting.com]. Fully updated and seemingly well
 maintained.

 '''Additional:'''
 There is a link from a 2.6 problem at
 [http://trinity777.wordpress.com/2008/10/28/wordpress-26-the-issue-of-wp-
 cronphp/]. Although it refers to an old version I think the issue is still
 unresolved and his work might prove useful to you.

 Thanks
