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: [...] [1279549983] nsd[26566]:

started [1279549991] nsd[26566]: warning: signal received, shutting down... 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.
