Job Manager logging thousands on huge transients?

Hello,

I have inherited a WordPress site that is using WP Job Manager. The database had grown to well over a gig, with ~30,000 entries in the wp-config table. It looks like every page load saves a new transient (understandable), but this site is logging the full WP_Query object (over 100,000 characters per record).

I nuked the transients with the following ham fisted approach on a dev database:

DELETE FROM foo.wp_options WHERE wp_options.option_name LIKE ('_transient_jm-%');
DELETE FROM foo.wp_options WHERE wp_options.option_name LIKE ('_transient_timeout_jm-%');

That dropped the wp-config table down to 40 MB from over 1 GB, but the site is still generating new entries.

Is there a way to keep this thing from logging like crazy?

The WP Job Manager plugin is version 1.21.2, and has the following companion plugins installed

– WP Job Manager – Contact Listing / Version 1.1.0
– WP Job Manager – Job Tags / Version 1.3.5
– WP Job Manager – Predefined Regions / Version 1.10.0
– WP Job Manager – WooCommerce Paid Listings / Version 2.4.0
– WP Job Manager Field Editor – Version 1.3.1
