Hi there,
We have been experiencing a problem with NSD (nsd-3.2.2-2.el5) and it's
init scripts on latest CentOS5:
After a
# service nsd restart
/var/log/messages reads:

After that, manually starting the service works fine and the
process comes up again.
It only happens after the daemon has been running for a while
(probably filling it's IXFR journal with changes) The server
is running as a slave (serving over +100k zones) using
TSIG/hmac-md5.
Config looks like:
server:
hide-version: yes
database: "/var/lib/nsd/nsd.db"
identity: "xxx"
logfile: "/var/log/nsd.log"
server-count: 1
tcp-count: 10
pidfile: "/var/run/nsd/nsd.pid"
statistics: 3600
zonesdir: "/var/lib/nsd"
difffile: "/var/lib/nsd/ixfr.db"
xfrdfile: "/var/lib/nsd/ixfr.state"
(Plus the regular TSIG stuff and the zone configs)
Could anyone please tell me more about the error messages above?
I was thinking that the init script tries too early to bring up
the daemon again - but obviously something else goes wrong in
the first place.
Thanks
Oliver
