I have done the following:
Checked bios time & system time. Both are the same (and correct)
I have scheduled a cron style task in FOG and am unable to find it in crontab. Have looked using the following commands (This is my very first attempt at anything cron, so if I am incorrect, please point me in the right direction)
ls /var/spool/cron
crontab -l -u fog
No jobs appear to be scheduled.
Manually scheduled a cron job with the following commands
crontab -e -u fog
created a job to rename a text file on my desktop. This executed successfully on time and the text file was renamed.

In the fog database I can look at the scheduledTasks table and see my scheduled tasks there.

Unfortunately, I don’t know enough about how FOG works with Ubuntu to create these tasks to understand WHY FOG is unable to successfully create the Cron job.

Hi everyone,
I’ve got FOG running on Ubuntu 11.10. I am attempting to use Scheduled Tasks to wake a group of lab computers up. I started out by attempting to schedule a Cron style task for the group. That didn’t work. The computers just didn’t turn on. I then went in and manually deleted (by truncating scheduled tasks in the database (instructions found on here)) the task.
After the cron style task didn’t work, I just assumed I messed up, so I tried scheduling single task for a single computer. That also didn’t work. I was able to view it in the Schedule Tasks page on the web interface. Once the time for the task to execute comes, the scheduled task vanishes and nothing happens.
So, I then thought the WOL just wasn’t working, so I tried to manually wake the computer up through fog. That worked fine.
Then I tried to schedule a single execution imaging task to the same computer. That doesn’t work.
If, however, I wanted to image that computer without scheduling it, I would be able to start the task and FOG would successfully wake the computer and start the imaging task.
Anyone have any ideas?

I’ll take a look and see if I’ve got one going bad. Thanks

I have a FOG server running .32 on a Ubuntu 11.10.

I am currently having issues when deploying images to computers. Fog was working great and then one day I came in and started having the following issues:

When deploying an image, FOG will begin to process and then randomly stall out. I get no error message, it just freezes on the imaging screen with the progress bar and stays there until I restart it. If I kill the task and start a new one, the same issue occurs.

This issue occurs across all computer models and with multiple images.

Occasionally, if I leave the imaging process running long enough (overnight) the task will complete, sometimes it will not. Prior to the stall I am getting excellent throughput. Upwards of 1Gb/min. The failure point is totally random. I can use the SAME image on the SAME computer and try three times, and it will stall in three different places, anywhere from 1% complete to 96% complete, eventually, if I try enough times, the task will complete. In the instances when the task completes, the image works great and has no problems.

I have changed default Kernels several times. I am currently running the default .32 kernel except on computers that seem to have issues with it.

I am hoping someone out there can give me a starting point as far as troubleshooting this goes. I can’t seem to find anything interesting in the log files and really need FOG to work again as I have several computer labs to re-image.
