[Samba] cups_async_callback(504) error after upgrade to 3.2.7

[Ed Kasky]

Hello there -

I just upgraded to 3.2.7 via an rpm from fedora - running fc6:
# uname -a
Linux yoda.wrenkasky.com 2.6.22.14-72.fc6 #1
SMP Wed Nov 21 15:12:59 EST 2007 i686 i686 i386 GNU/Linux

Since upgrading, I am getting the following every hour or so:
[2009/01/07 15:19:08,  2] printing/print_cups.c:cups_async_callback(504)
   cups_async_callback: failed to read a new printer list

There's not much in the archives to this particular error
that seemed to apply directly in this instance.

We have just one printer configured through samba:

[global]
         load printers = yes
         printing = cups
         printcap name = cups
         cups options = raw

[printers]
         comment = All Printers
         path = /var/spool/samba
         printable = Yes
         browseable = No

[HP4050]
         comment = HP4050 on Yoda
         path = /var/spool/samba
         guest ok = Yes
         printable = Yes
         printing = cups
         print command =
         lpq command = %p
         lprm command =
         printer name = Hp4050

I have tried rebooting and failing that, restarted cups and the smb 
daemons but to no avail.

Anyone have any suggestions as to where I should look next?

Thanks!
