Hi! We use the PowerDNS Auth control socket with TCP from another host extensivly to trigger "retrieve" requests. Several times a day we get the follwing error:
# pdns_control --remote-address=... --remote-port=... --secret=... retrieve example.com Timeout error: Error from remote in receive(): Resource temporarily unavailable I analyzed the problem with tcpdump and following happens: * pdns_control established the TCP connection * pdns_control sends the secret and the command * 7 seconds later pdns_control gives up waiting and closes the TCP conenction (FIN) * another 1 second later the server responses with "Added retrieval request ...." Hence, the problem is that PowerDNS is sometimes very slow adding the retrieval request. Do you have an idea why this happens? Are there some internal locks? Any ideas how to debug this to find the problem for the slow reaction? This PowerDNS instance is well loaded (having almost 1Mio slave zones) Thanks Klaus _______________________________________________ Pdns-users mailing list [email protected] https://mailman.powerdns.com/mailman/listinfo/pdns-users
