You found app_stamp, that's microseconds epoch

No way to limit the info, also this info is very handy for figuring out
what took place after the fact.

Syslog for CDR? Just load mod_syslog and configure it for logging.  You
should use the post method with fallback and isolate the CDR processing
infrastructure and not intermingle that into syslog.

Do you currently experience this 'workload' that is impacting anything?  I
want to make sure you're not wasting your time trying to wax your car to
get better gas mileage.
