Description Jürgen Holm 2013-10-21 12:41:39 UTC 
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...

Version-Release number of selected component (if applicable):
1.0.40-3.fc19.x86_64

How reproducible:
always

Steps to Reproduce:

Expected results:


Additional info:
No problems with 1.0.34-7.fc19.x86_64

Temporary fix:
cat <<EOF >/etc/cron.hourly/restart-cups-browsed
#!/bin/bash
systemctl start  cups-browsed.service
EOF
chmod a+x /etc/cron.hourly/restart-cups-browsed
Comment 1 Tim Waugh 2013-10-21 13:00:14 UTC 
Please attach /etc/cups/cups-browsed.conf.

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

Created attachment 814606 [details]
cups-browsed.conf

The host to poll cups resolves:
Enterprise: ~>host cups
cups.theorie.physik.uni-goettingen.de has address 134.76.88.193
Comment 4 Tim Waugh 2013-10-21 13:41:35 UTC 
Thanks.

I think I've found the leaks.
