Escalate Priority

We’re running RT3.2.3 on MySQL 4.0.20, RHEL3, Apache 1.33, mod_perl 1.29.
Using rt-crontool to call Escalate Priority every business day. Each queue
is configured to start priority at 11 and increase to 99.

The escalate priority formula changes the priority to 99 on the day PRIOR
to the ticket being due. I thought it should change priority to highest
priority specified in the queue config on the actual due date.

Any recommendations for changes to, or anything else to
correct this?

We also use rt-remind called from cron to generate a daily reminder to the
owner whenever the priority reaches 99, under the assumption 99 would only
be reached on the due date.

Thanks for any suggestions,
