at/batch subsystem time limit

[Jim Pazarena]

Is there a upper execution (or real) time limit that the system
enforces on at jobs?

I have an at job which would run for at least two hours .. IF it would
run to completion, but it always seems to die for unknown reasons.
I do not get an email or any advice of the reason the job has terminated.

So I was thinking that there may be a kernel timer which kills the job.

is this possible?
