I submitted a job that, I think, should have returned 100 emails from JPL Horizons.

I now have over 6000 emails and they are coming in at about four a minute.

Anyone else had this problem?

Anyone know how to stop the deluge?

I have emailed JPH Horizons default email address.

Details

  • Initial PID = 3073788 Thu May 4 09:40:31 2023 UTC
  • Request started: COMMAND = '1;' '2;' '3;' '4; at 09:38

Latest email to arrive starts:

Automated mail xmit by MAIL_REQUEST, PID= 272715 Thu May 4 04:16:09 2023

Initial request was for the first 100 asteroids ('1;' '2;' etc.) with these parameters:

    $\begingroup$ BTW, the SPK ID system for asteroids is being expanded to allow for more bodies. But it looks like the old IDs will continue to work properly. See the Horizons News item for Mar 21, 2023 for details. ssd.jpl.nasa.gov/horizons/news.html $\endgroup$

It turns out the "more robust" mail queue manager implemented April 21 has a condition where it can rediscover itself. That condition occurred in the middle of the night local time with your query.

The good news is it was fixed yesterday. The bad news is 49K emails were already sent before someone else entered the mail queue and it let go and moved on normally.

The "four per minute" is just your local system gradually leaking yesterday's pathology in. Recommend purging the accumulation from your delivery queue if you have the level of control. If not, redirect duplicate emails from Horizons to trash until it clears.

If consolation, about 150K messages were received here from your system explaining it can't deliver X for the last four hours, but it will keep trying for the next five days, each with a copy of the as-yet undelivered email.
