Comment 0 for bug 2018504

It could be a problem with the network, but I'm seeing cups-browsed appearing to keep one CPU core busy. This seems surprising, since I'd only expect it to be doing something when printers are advertised over mDNS.

It may be unrelated, but I'm also seeing warnings like the following in the journal:

These errors seem to be generated when glib's g_source_remove() function is called with an ID for a job that doesn't exist. This could indicate that cups-browsed is losing track of an idle or timeout function.
