Description Jürgen Holm 2013-10-21 08:41:39 EDT
Description of problem:
With cups-filters-1.0.40-3.fc19.x86_64 I got many (currently ~300 ) CLOSE_WAIT connections
tcp        1      0 Enterprise.theori:58593 cups.theorie.physik:ipp CLOSE_WAIT  1010/cups-browsed   

and ~6 ESTABLISHED connections:
tcp        0      0 Enterprise.theori:33139 cups.theorie.physik:ipp ESTABLISHED 1010/cups-browsed  

Because of this our cups server, responseable for ~100 clients breaks with MaxClients too low: Max clients reached, holding new connections...

How reproducible:

Additional info:

Temporary fix:
cat <<EOF >/etc/cron.hourly/restart-cups-browsed
systemctl start  cups-browsed.service
chmod a+x /etc/cron.hourly/restart-cups-browsed
Comment 1 Tim Waugh 2013-10-21 09:00:14 EDT
Please attach /etc/cups/cups-browsed.conf.

It looks like the IPP subscriptions code has a socket leak somewhere. :-(

Created attachment 814606 [details]

The host to poll cups resolves:
Enterprise: ~>host cups
cups.theorie.physik.uni-goettingen.de has address
Comment 4 Tim Waugh 2013-10-21 09:41:35 EDT

I think I've found the leaks.
