VOW Account/Data Disabled

asked 2021-02-24 13:36:10 -0500

About two weeks ago we changed from a dedicated server to a shared VPS for our VOW. Things have worked/updated on the site fine for the last two weeks. Today we received a note form our MLS director with the following from Paragon. Is there anything specific I can do to address this issue and get the data flowing again?

"Michael, I have been informed by Paragon that they have disabled your VOW account for the following reason:

2070305 - Michael Lancsek VOW

This user is running millions of search queries per day that do not return any results due to their astronomically high offset values such as 82010000. The MLS only has 76k listings total in the database, so the specified offset would never need to be that high.

To reactivate your account Paragon is asking that you adjust your query to limit the number of searches."

Your account was causing excessive server load because of the endless search transactions.
You were sending over 5 Million search transactions in a 24 hour period that started 2/19.
I saw offsets as high as: 2,147,470,000 running on two different overlapping sessions.
When using the offset/limit functionality make sure to terminate your loop when the search is no longer returns records. Or the search ReplyCode is no longer 0.
Don't rely on record count as a terminator for a loop because it can vary because the data is constantly changing.
