This is a standard behavior from a Max (usually when you reboot or reset
a config). Check the MAX documentation on how to turn this off. It
was recently posted here on the list as well (check the archives).

You would have to run RadiusNT in -x15 to really see whats going on during that
time. I would guess you are having a SQL Server issue where RadiusNT gets
hung or held up by another task (like someone doing an intense query on your
sql server, or deleting records from the calls table). The dual thread
operation of RadiusNT 2.5 should help the later, but you may need to profile
your SQL Server (performance monitor) and try and track down who/what is
