[cups.development] [RFE] STR #1535: When a process except cupsd uses the port 631, Samba which enables CUPS can't boot.

[STR New]

I find a problem about the CUPS function of Samba.

When the cups daemon doesn't work and the port 631 is used by another
process, the smbd which enables the CUPS function can't boot.

Even if the port 631 has already used by another process, the smbd
connects to the 631 port for the initialisation of CUPS.
And the smbd stalls in the cupsDoRequest().

Because the current implementation of cupsDoRequest() doesn't have any
timeout mechanism, it may be difficult to avoid this situation.
I think it needs a enhancement to verify the server daemon or detect the
timeout.

I filed this problem to a Bugzilla of Samba.
