I can't recall if I've answered this one already for you. Unfortunately,
I found that my spam filter had incorrectly removed this from my Inbox.
I apologize for the long wait if you have not received an answer yet.

Reservations should fail. Charges should succeed. Let me know if this is
not what is happening.
The theory is that when you are deciding whether to start a job, you do
not want to start it if there are not enough funds, so you should reject
the reservation request and the resource manager should normally not
start the job (as a side note, some schedulers, such as Moab, can be
configured to run the job even if the reservation fails).
Once a job has actually run and used actual resources, you probably want
to record the usage, even if it makes the account go negative. If this
happens, then something else went wrong (the job run past its wallclock
limit, or a withdrawal was made to your account before the job could
complete, etc). It doesn;t do you much good to use the cycles and throw
away the accounting and not charge for it. It has to be accounted for.
If this happens on an account with CreditLimit of 0, we need to figure
out what else is going wrong to allow the job to get started when it
should not have had enough credits to do so.
