I'm using Linux [ RHEL 5] , our team manages printing via this server , the printing uses CUPS 1.3.7 .
We experienced very reliable printing for more than a year and a half , but since last 2 weeks our printing is delayed intermittently and queues are getting disabled , we need to use scripts to enable it by running cronjobs .
While we checked the error logs , it showed the below message a lot of times for multiple queues "DNS-SD registration of "printer_queue1" failed with -65548" We have etc/resolv.conf file with the correct active DNS server's IP . When we do NS look-up as a loop continuously, there is no lapse and also it shows the primary DNS is used to resolve the name to IP .
No changes are performed to the CUPS or at network level .
Is there a possibility for cups to multicast [mdns] the hostname, in order to resolve the IP instead of using the /etc/resolv.conf
file.
when I grep in ps -ef
command to get the process of connectivity

Please share your thoughts like why the -65548 error occurs and possible chances of delay within CUPs processing a job or queues getting disables intermittently .
