Hi Adrian,
You are right, the IPC server could not be reached. Every scheduled task calls the bSchedStarter process when it triggers. We have about 45 individual backup jobs that run throughout the night and they have been running flawlessly every night, so I don't think it has anything to do with our antivirus.
What I did was take 7 of those existing jobs and delete the scheduled time for each of them. I then created a tag and added those 7 jobs to it. I made no other changes to the jobs themselves. Then, in the B4A scheduler, I created a task to back up that tag of 7 jobs. That task ran, and the files backed up, but subsequent tasks/jobs did not.
Here is the last few lines from the log of the "tag" job:

Here is the last few lines from the bSchedStarter log for the "tag" job:

And here is the last few lines from the bSchedStarter log for the very next job scheduled after the "tag" job:

-----------------------------------------------------------------------------------------------------
So, logic would dictate that something in the act of processing the tag job stopped the service. After I sent my first message, I deleted the scheduled tag job in the B4A scheduler, removed the backup jobs from the tag and deleted the tag itself. I then rescheduled each of the 7 jobs individually as they were before and the entire backup (all scheduled jobs) ran perfectly.
I can certainly continue scheduling jobs individually, it just seemed that it would be a little more efficient to use tags. I'm functional now, but this is just something for you to think on.
