When I try to edit and save some classes on sandbox, I receive an error "Schedulable class has jobs pending or in progress".
When I go to schedulable job list, I see empty list (no scheduled job).
When I asked salesforce support they replied to me that there is still one scheduled job with State 'ACQUIRED' with null instead CronJobDetail (so, no JobType neither Name).
When I tried to follow their advice and remove that job, I received an error "Job does not exist or is already aborted".
More over, when I try to open Owner\CreatedBy of this job, I see "Insufficient Privileges You do not have the level of access necessary to perform the operation you requested. Please contact the owner of the record or your administrator if access is necessary."
When I query this user by its id (Select Name from User where Id = ...), no results are returned.
Any thoughts how this can be possible at all?
Does that mean that we will have to ask salesforce support to remove this mystical job from all sandboxes each time after refresh?..
