Why does MySQL error appear on the site after exchanging data with 1C?

Question

1C-Bitrix

There was a problem when exchanging goods between 1C and Bitrix. Initially, a certain number of product properties were introduced in 1C, which were uploaded to the site.
Then we added new properties to the products and an error began to appear after the data exchange.

When the number of properties for a product exceeds 100, then on the site side in the product card after the exchange, a MySQL error message appears (Too many tables: MySQL can only use 61 tables...). "Extra" properties have to be deactivated in the admin panel so that the site starts to display normally.

What could be the reason for the error?
