Almost permanently problem "dns lookup for xxxx timed out"
Hello, i've got problem to connect to some users. Problem is partly random and partly permanent. It's not ease to describe all cases. Permanently i can't connect to users in domain: gmail.com. On roster i have info "remote-server-not-found", in s2s.log i have "dns lookup for gmail.com timed out". 1. First case, gmail is unreachable, in s2s debug log there is: [...] sx (io.c:240) decoded read data (1024 bytes): http://jabberd.jabberstudio.org/ns/component/1.0' from='mejor.pl' to='gmail.com'> Mon Jan 16 15:31:58 2012 out.c:403 trying to find connection for 'gmail.com' Mon Jan 16 15:31:58 2012 out.c:406 connection for 'gmail.com' not found Mon Jan 16 15:31:58 2012 out.c:412 no dns for gmail.com, preparing for resolution Mon Jan 16 15:31:58 2012 out.c:440 requesting resolution for gmail.com Mon Jan 16 15:31:58 2012 out.c:1177 dns resolve for gmail.com@0x7f1fc3d5dc60 started Mon Jan 16 15:31:58 2012 out.c:839 dns request for gmail.com@0x7f1fc3d5dc60: SRV xmpp-server Mon Jan 16 15:31:58 2012 out.c:117 creating new out packet queue for 'mejor.pl/gmail.com' Mon Jan 16 15:31:58 2012 out.c:125 queueing packet for 'mejor.pl/gmail.com [...] Mon Jan 16 15:31:58 2012 out.c:1177 dns resolve for gmail.com@0x7f1fc3d5dc60 started Mon Jan 16 15:31:58 2012 out.c:839 dns request for gmail.com@0x7f1fc3d5dc60: SRV xmpp-server [...] Mon Jan 16 15:31:58 2012 out.c:815 dns response for gmail.com@0x7f1fc3d5dc60: SRV _xmpp-server._tcp.gmail.com 5 (842) Mon Jan 16 15:31:58 2012 out.c:822 dns response for gmail.com@0x7f1fc3d5dc60: SRV _xmpp-server._tcp.gmail.com[0] alt4.xmpp-server.l.google.com/5269 (20/0) Mon Jan 16 15:31:58 2012 out.c:793 dns host added for gmail.com@0x7f1fc3d5dc60: alt4.xmpp-server.l.google.com/5269 (20/0/842) Mon Jan 16 15:31:58 2012 out.c:822 dns response for gmail.com@0x7f1fc3d5dc60: SRV _xmpp-server._tcp.gmail.com[1] xmpp-server.l.google.com/5269 (5/0) Mon Jan 16 15:31:58 2012 out.c:793 dns host added for gmail.com@0x7f1fc3d5dc60: xmpp-server.l.google.com/5269 (5/0/842) Mon Jan 16 15:31:58 2012 out.c:822 dns response for gmail.com@0x7f1fc3d5dc60: SRV _xmpp-server._tcp.gmail.com[2] alt1.xmpp-server.l.google.com/5269 (20/0) Mon Jan 16 15:31:58 2012 out.c:793 dns host added for gmail.com@0x7f1fc3d5dc60: alt1.xmpp-server.l.google.com/5269 (20/0/842) Mon Jan 16 15:31:58 2012 out.c:822 dns response for gmail.com@0x7f1fc3d5dc60: SRV _xmpp-server._tcp.gmail.com[3] alt2.xmpp-server.l.google.com/5269 (20/0) Mon Jan 16 15:31:58 2012 out.c:793 dns host added for gmail.com@0x7f1fc3d5dc60: alt2.xmpp-server.l.google.com/5269 (20/0/842) Mon Jan 16 15:31:58 2012 out.c:822 dns response for gmail.com@0x7f1fc3d5dc60: SRV _xmpp-server._tcp.gmail.com[4] alt3.xmpp-server.l.google.com/5269 (20/0) Mon Jan 16 15:31:58 2012 out.c:793 dns host added for gmail.com@0x7f1fc3d5dc60: alt3.xmpp-server.l.google.com/5269 (20/0/842) Mon Jan 16 15:31:58 2012 out.c:1077 dns ttl for gmail.com@0x7f1fc3d5dc60 limited to 842 Mon Jan 16 15:31:58 2012 out.c:1088 dns request for gmail.com@0x7f1fc3d5dc60: A alt1.xmpp-server.l.google.com Mon Jan 16 15:31:58 2012 out.c:1249 read action on fd 11 sx (io.c:191) 11 ready for reading sx (io.c:197) tag 11 event 2 data 0xc3d9e7a0 Mon Jan 16 15:31:58 2012 out.c:1401 reading from 11 Mon Jan 16 15:31:58 2012 out.c:1445 read 186 bytes sx (io.c:216) passed 186 read bytes sx (chain.c:93) calling io read chain 2.
