First thing I tried before posting. It gets two hits: The first hit is from 20 years ago and basically says "don't worry about it" while referring to a man page I don't understand. The second hit points to a RedHat page that wants me to create an account to access their knowledge base for RHEL. poc

Maybe post your subscriptions.conf and see if someone does know what it means? That first post seems to imply that there is config asking for notifications every seconds. But this is not something I have every setup myself. Barry

Looks like a config error on my part which I'll look at. 2) The Interval entry is 0 in both cases, though I've no idea why. That probably explains the 1-second frequency of journal entries. The man page says that this file is maintained by cupsd and should not be user-edited. The cupsd(8) page is just an anchor for a whole bunch of other pages which I will have to investigate. poc

Search engines curate results depending on your search history (my wife and I get completely different results for many searches). Adding terms to your search and setting a time range may help.

You can create a free account. The RHEL knowledge base is nearly as useful as arch linux documentation, so well worth the effort to create a free account (you will probably want to disable most of the emails). -- George N. White III

The search was fairly explicit but sure.

Did that (despite qualms about having to register my home address and phone number - why do they need this?) and still no dice. I get a page saying: Subscriber exclusive content An active Red Hat subscription is required to participate. poc
