In the file /var/log/message I find a lot of messages:
… liblogging-stdlog: imuxsock[pid 2608]: begin to drop messages due to rate-limiting
… liblogging-stdlog: imuxsock[pid 2608]: 13 messages lost due to rate-limiting
Process 2608 is /usr/sbin/named => BIND 9.10.3.P4-Univention
There are a log of informations from processs 2608 in /var/log/syslog but no warnings or error messages.
The value of dns/dlz/debug/level and dns/debug/level is 3.
Is this the default value ?
By the way there is no tag ucs4-4.
Thanks and regards
Rainer
