I recently put together a script to collect Event 703 information for analysis of online maintenance. After looking at the data, the run time in seconds is longer than the duration from the "Started on" attribute of the job to the TimeGenerated attribute. All information taken from the ReplacementStrings collection of the Event object, as displayed in the "Message" attribute. Does this value perhaps represent cumulative time spent by multiple threads? Scratching my head...

Hi Thank you for your question. I am trying to involve someone familiar with this topic to further look at this issue. Terence Yu TechNet Community Support

Hi CBS3, Yes it is cummulative and it is value for all the invocations it made. To help you understand better, Online Defragmentation has completed a full pass on database %database file name%, freeing %number of pages freed% pages. This pass started on %OLD start date% and ran for a total of %total number of seconds actively running OLD against database% seconds, requiring %number of invocations% invocations over %number of days% days. Since the database was created it has been fully defragmented %total OLD completions% times over %number of days since database was created% days. Does this help? Thank you Santhosh
