Ticket #108 (closed defect: fixed)
outgoing AXFR fails with large zones
|Reported by:||anon||Owned by:||somebody|
We have a dns setup with ns1 served by powerdns, ns2 and ns3s are bind9, which are our slaves and get their zones by AXFR. PowerDNS is configured with the gmysql backend against a locally running mysql (4.1.11a-4sarge2).
dig @ns1... AXFR large.zone shows after 301 records:
;; communications error: end of file
PDNS log shows:
Nov 21 15:08:24 ns1 pdns: AXFR of domain 'large.zone' initiated by cli.ent.ip.xxx Nov 21 15:08:24 ns1 pdns: TCP server is without backend connections in doAXFR, launching Nov 21 15:08:24 ns1 pdns: gmysql Connection succesful Nov 21 15:08:24 ns1 pdns: gmysql Connection succesful Nov 21 15:08:34 ns1 pdns: TCP nameserver had error, cycling backend: Trying to read data from remote TCP client cli.ent.ip.xxx: Resource temporarily unavailable
With 2.9.20 the AXFR worked, but after some time we saw that problem with tcp connections hanging open...
