Check whether the process is running the Delete Processing Status Report. You can check this by viewing the log in Schedule Administration or under Submitted Jobs.

Delete Processing can generate an enormous amount of data if run against large tables or many tables, so the report can run for a very long time and sometimes stall.  If the report is not needed, we suggest you kill the process in Schedule administration. You can prevent the report from running in the future by setting the system preference, under Schedule Administration >> Procedures >> Delete Processing for the Disable Delete Processing Status Report preference to "Y".
