CUPSD AutoPurgeJobs does not purge job history data

Hello

I do not need old job history data after print request has ended successfully. That why I recently updated /etc/cups/cupsd.conf and activated AutoPurgeJobs Yes . After that I restarted cupy using systemctl restart cups . But nevertheless /var/spool/cups/ still fills up and I have to delete old jobs manually with the command sudo rm /var/spool/cups/c* .

What might be be wrong with AutoPurgeJobs Yes ? Man-page explains “Specifies whether to purge job history data automatically when it is no longer required for quotas. The default is “No”.” How is “no longer required for quotas” calculated? Is ‘quotas’ the reason why /var/spool/cups/ still fills up?

Thank you in advance.

Sorry, in between I helped myself by adding additional parameters in cupsd.conf:

PreserveJobFiles 86400
PreserveJobHistory 86400

Seems to purge now.
