[cups] cupsd using 100% of CPU with v2.2.1-8

[Emma Simon]

Hi,

I've been working on this issue for a while now and am having trouble
solving on my own. Google isn't helping with, other people have had similar
problems, but none of those solutions worked for me. Hopefully someone on
here can help me figure out what's up.
I'm running cups v2.2.1-8 on Debian 9, and it's almost constantly using
100% CPU. It sometimes stops for a few seconds, up to a few minutes, but
then goes right back up to 100%. I've tried many restarts, uninstalling and
building v2.2.2 from source, then uninstalling that and going back to the
version that Debian supports. The error_log contains thousands of lines of
the following:

W [08/Mar/2017:16:27:39 -0500] CreateProfile failed:

With new ones being added every few seconds. I assume this has something to
do with the CPU usage, but I have no idea what's causing the errors.
If you need any other information, please let me know, I'm not entirely
sure what's relevant at this point.

Thanks!
