[Pkg-cups-devel] Bug#669092: cups: Connection to server is not reestablished when using BrowsePoll and connection is interrupted

Package: cups
Version: 1.5.2-5
Severity: normal

When using BrowsePoll to discover printers on a defined remote server, CUPS uses a TCP connection,
which is fine but may in some cases break.

One scenario is a client going to sleep (in terms of ACPI). When it comes back up, the conenction
has timed out on the server side and following attempts by the client to poll are answered with
a connection reset by the server.

The client CUPS daemon should now try to re-establish the connection, but doesn't. No new connection
is ever made until cupsd is restarted.
