[cups.bugs] [HIGH] STR #1786: Raw printing to a networked CUPS server is broken

[Roger Leigh]

[STR New]

Printing to a local queue with

lpr -P <printer> -oraw <file>

works fine, but when <printer> is a printer discovered by browsing,
the local cupsd sends a lot of network traffic for several minutes,
and then cupsd dies.  The remote cupsd never receives the job.

>From the log, it looks like it used up all available file descriptors;
netstat shows many IPP connections, mostly TIME_WAIT. It looks like it
tried sending the job many many times over; I think this is only the final
few tens of retries.

I've attached the error log.
