After applying the workaround I have created 10000 print queues with the
following command line
x=0; while [[ $x != 10000 ]]; do lpadmin -p 0000$x -E -v
dnssd://CM3530%20%40%20eee-pc._ipp._tcp.local/cups; echo $x; x=$(( x + 1
)); done
checked whether they are really there
lpstat -v | wc -l
and removed them:
x=0; while [[ $x != 10000 ]]; do lpadmin -x 0000$x; echo $x; x=$(( x + 1
)); done
All the time it was able to do several queues per second (up to around
10) and CUPS did not crash during this rapid fire. gnome-settings-
daemon, system-config-printer-applet, and system-config-printer keep
running and do not crash. They simply have a higher CPU consumption, the
former two for notifying on the desktop the latter for updating its main
window (being unresponsive though) under this torture.
So this shows that the workaround is OK. I will apply it.
