Thanks for these suggestions.
egrep '(Limit|Period)' /etc/cups/printers.conf produces:

# Printer configuration file for CUPS v1.1.17
# Written by cupsd on Sat 12 Aug 2006 03:29:28 PM GMT
<DefaultPrinter lp0>
Info Created by redhat-config-printer 0.6.x
DeviceURI parallel:/dev/lp0
State Idle
Accepting Yes
JobSheets none none
QuotaPeriod 0
PageLimit 0
KLimit 0

I do not see anything here or in the manual that would help.  The puzzle 
is: why did it suddenly start after months of normal operation?
