I'm getting an error "data area passed to a system call is too small" when trying to add a task to the Windows Scheduler. We currently have about 20 tasks in it.

Googling the issue, we found to stop/start the task service, wait, and some kind of clean-up would be run. We've done this multiple times and it's not fixing anything. Even if we delete a task, we can not re-add one.

Has anyone seen this problem and how did you fix it?

Task Scheduler returns a "HRESULT: 0x8007007A" error message after you save many jobs:

To work around this behavior, stop and start the task scheduler service, wait for 10 to 15 minutes, and then schedule jobs.

There is a scavenger tool in task scheduler that runs 10 minutes after the service is started. This tool frees the memory that is still being used by deleted or scheduled jobs.

How long did you wait?

Alternatively, try to delete the following reg key:

10, 20, 30, and 60 minutes. This does not fix the problem for me. – CDTX Mar 11 '12 at 1:04
have you checked to see if you've got any tasks running against a user/program that doesnt exist anymore? If you have, delete it! – G Koe Mar 11 '12 at 6:24
@G Yes, we've removed all tasks that aren't needed. There's got to be something else that's wrong. We're only talking about 20 tasks or less that are currently set up. – CDTX Mar 11 '12 at 15:47
