Hello,
I am running a cups server which works as expected, but I just realized that
the error log show a tremendous amount of entries:
root@home:~# tail /var/log/cups/error_log
E [19/Nov/2020:16:14:00 +0100] [Client 49726] Empty Basic password.

E [19/Nov/2020:16:14:02 +0100] [Client 49753] Empty Basic password.
root@home:~#
Digging further, I realized that cupsd keeps one core of the server busy
PID USER PR NI VIRT RES SHR S %CPU %MEM TIME+ COMMAND
28032 root 20 0 82452 14572 5828 R 98.0 0.7 50:14.12 cupsd
The error log entries stops, if I poweroff another Debian system with cups
running as a client
rd@h370:~$ cat /etc/cups/client.conf
ServerName 192.168.7.1
rd@h370:~$
On the client side, I do not see corresponding log entries:
rd@h370:~$ cat /var/log/cups/error_log

rd@h370:~$
Is there anything wrong with my setup? As I wrote before, I see no functional
problem.
Any advice or hint is welcome.
Thanks
Rainer
