[cups.bugs] Socket backend communication problem Kyocera IB-20 IB-21 network cards

[William Crowell]

CUPS 1.2.6
GLIBC 2.4, 2.5
GCC 4.1.1
Kernel 2.6.18.2
(Gentoo Base)
All Kyocera printers using IB-20/IB-21 network adapters with socket connection 
to 9100.

First print job will process most of the time. Subsequent print jobs produce 
no output. Something in the socket communication is causing the Kyocera cards 
to hang. Power-cycling the printer will reset for the next job.

*This is not a problem with running multiple copies of a single job.*

/var/log/cups/error_log shows messages about "discarded events" from the 
socket backend.

This problem does not occur with LPRng.
