cups problems

[Ishark]

Hello,

after the upgrade to 2007, it looks like cups has become "read-only": all printers installed before the upgrade work fine, but any attempt to access the "administration" tab in the web interface locks up the daemon (actually, it locks up a backend).

I've tried also on a friend's PC, where 2007 was installed from scratch (and not an upgrade like me) and it's the same effect. A search on this forum showed some problems, solvable by upgrade. I then cleaned my cups setup (removed rpms, cleared configuration files) and reinstalled the latest packages:

 

>rpm -qa | grep cups

cups-1.2.4-1.1mdv2007.0

cups-common-1.2.4-1.1mdv2007.0

libcups2-1.2.4-1.1mdv2007.0

libgnomecups-0.2.2-3mdv2007.0

cups-drivers-2007-6mdv2007.0

 

it still locks up if I try to access the "administration" tab.

The pending processes are:

 

root 353 8.4 0.1 6348 1984 ? Ss 17:13 0:04 cupsd

root 397 15.7 0.1 6356 2000 ? Ss 17:13 0:04 cupsd

lp 418 0.0 0.1 3384 1296 ? S 17:14 0:00 /usr/lib/cups/cgi-bin/admin.cgi

lp 419 0.0 0.0 3160 872 ? S 17:14 0:00 /usr/lib/cups/daemon/cups-deviced 1 0 4 requested-attributes=all

root 442 0.0 0.1 3304 1120 ? S 17:14 0:00 /usr/lib/cups/backend/snmp

 

and the 2nd one is eating up 100% cpu.

I've tried to enable maximum debug information in the logs, but it's useless. I get no more information than in normal mode, i.e.:

 

I [09/Nov/2006:17:16:22 +0100] Started "/usr/lib/cups/cgi-bin/admin.cgi" (pid=515)

I [09/Nov/2006:17:16:23 +0100] Started "/usr/lib/cups/daemon/cups-deviced" (pid=516)

W [09/Nov/2006:17:16:54 +0100] [cups-deviced] Backend "snmp" did not respond within 30 seconds!

 

Which doesn't tell me why the snmp backend is locked up.....

 

Any suggestion? Should I dump this cups version and try to reinstall the packages from 2006?
