An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /batch?id=166&op=do StatusText: Service

Upon running a bulk batch for Location Taxonomize (for Address Field), I'm receiving this error which prevents it from completing:

An AJAX HTTP error occurred. HTTP Result Code: 500 Debugging information follows. Path: /batch?id=166&op=do StatusText: Service unavailable (with message) ResponseText: PDOException: SQLSTATE[HY000]: General error: 1366 Incorrect integer value: '' for column 'status' at row 1: UPDATE {signature_forum_post} SET type=:db_update_placeholder_0, delta=:db_update_placeholder_1, status=:db_update_placeholder_2 WHERE ( (type = :db_condition_placeholder_0) AND (delta = :db_condition_placeholder_1) ); Array ( [:db_update_placeholder_0] => node [:db_update_placeholder_1] => 2 [:db_update_placeholder_2] => [:db_condition_placeholder_0] => node [:db_condition_placeholder_1] => 2 ) in _signature_forum_object_update() (line 936 of /home/ecudchi/public_html/v02/sites/all/modules/signature_forum/signature_forum.module).

This may have also pointed me to the module that has been causing some other AJAX problems across the site! Fingers crossed on that one. :)

So I'm now disabling this signature_forum module until this is fixed. Hopefully someone finds this information useful and can easily pinpoint the problem and provide a solution.
