[cups.bugs] [HIGH] STR #1922: Print requests coming in via cups-lpd get lost while cups restarts

[Peter Prasnik]

[STR New]

We have cups 1.1.23 on RHEL 3.0. 

Occasionally, for whatever reason, cupsd "hangs" until it is restarted. 
Well, we deal with this by using monit to periodically check if cups can
be accessed via Port 631 over the network. If not, monit restarts cups. 
This far, well and good BUT: 

Customers report that print requests get lost if cups is restarted while
they are being processed.  
These print requeset get sent to the cups server vi lpr. cups-lpd accepts
them returnig 0 to the sending machine, but if during this process cups is
restarted at the right moment, the print request is discarded befor it can
be processed by cupsd.
