[galaxy-dev] jobs don't get killed when histories deleted

Hi all, It seems that this problem has been reported before http://dev.list.galaxyproject.org/jobs-don-t-get-killed-when-histories-delet... and should be solved https://trello.com/card/jobs-stop-job-function-in-jobs-admin-interface-is-br.... However I am using the Apr-2014 version (at least the version with the fancy Load Data button at top of tools panel which is a quite new feature). The jobs from deleted histories still hang around in the manage jobs admin page with some cannot-finish setting_metadata jobs. The interesting thing is that the last update time is always less than 24 hours. How to delete these unwanted jobs? Best regards! Jun
