Deadlock when using Job Queues

Hello i am having a problem related to Job Queues and i would very much appreciate it if you could help me out.

Here is the problem:

I have created two separate Job Queues:


And their cards:


The first Job Queue is created for running a Codeunit every 3 minutes and the second for running a report once every day.


The problem is that every once in a while, for some unknown reason the second Job Queue stops and i have to restart it. I dont undestand why this is happening. The error in the event viewer is the following:

Both Job Queues run with the same user, who is a SUPER user.
The only thing i have noticed is that the error happens while the first Job Queue is running. I dont understand why those two Job Queues have a conflict with each other, since i have configured the first Job Queue Entry to run until 9pm and the second to run only every day at 10pm. Why does the message say that another user is modifying the Job Queue Entry table, since those two Jobs never run at the same time?

Any help would be very much appreciated!
