Hi all, After running opensips for a while (one or two days), I got this log message:
*INFO:core:send2child: no free tcp receiver, connection passed to the least busy one (46)* *INFO:core:probe_max_sock_buff: using snd buffer of 509 kb* Then I checked the number of tcp connections: #*opensipsctl fifo list_tcp_conns* It displayed about 145 connections, but it's impossible since this is the testing server only. Here are all the output: ----------------------------- Connection:: ID=1203 Type=tls State=18446744073709551615 Source= 67.21.5.36:12497 Destination=sip_test_ip:5061 Timeout=2014-12-02 01:33:26 Pending lifetime=135250 Connection:: ID=1206 Type=tcp State=3 Source=162.236.129.149:62237 Destination=sip_test_ip:5060 Timeout=2014-12-03 14:10:18 Pending lifetime=0 Connection:: ID=1214 Type=tcp State=3 Source=162.236.129.149:62272 Destination=sip_test_ip:5060 Timeout=2014-12-03 14:24:18 Pending lifetime=0 Connection:: ID=1221 Type=tls State=0 Source=67.21.5.36:61790 Destination=sip_test_ip:5061 Timeout=2014-12-03 15:38:27 Pending lifetime=137101 Connection:: ID=1222 Type=tcp State=3 Source=172.56.38.226:46235 Destination=sip_test_ip:5060 Timeout=2014-12-03 14:41:55 Pending lifetime=0 Connection:: ID=1223 Type=tcp State=3 Source=172.56.38.226:27013 Destination=sip_test_ip:5060 Timeout=2014-12-03 14:43:36 Pending lifetime=0 Connection:: ID=1224 Type=tcp State=3 Source=162.236.129.149:62314 Destination=sip_test_ip:5060 Timeout=2014-12-03 14:45:10 Pending lifetime=0 Connection:: ID=1225 Type=tcp State=3 Source=162.236.129.149:62327 Destination=sip_test_ip:5060 Timeout=2014-12-03 14:48:55 Pending lifetime=0 Connection:: ID=1226 Type=tcp State=3 Source=162.236.129.149:62344 Destination=sip_test_ip:5060 Timeout=2014-12-03 14:59:33 Pending lifetime=0 Connection:: ID=1227 Type=tcp State=3 Source=162.236.129.149:62352 Destination=sip_test_ip:5060 Timeout=2014-12-03 15:04:56 Pending lifetime=0 Connection:: ID=1228 Type=tcp State=3 Source=162.236.129.149:62366 Destination=sip_test_ip:5060 Timeout=2014-12-03 15:15:34 Pending lifetime=0 Connection:: ID=1229 Type=tls State=3 Source=67.21.5.36:26619 Destination=sip_test_ip:5061 Timeout=2014-12-03 15:16:41 Pending lifetime=0 Connection:: ID=1230 Type=tls State=3 Source=67.21.5.36:22292 Destination=sip_test_ip:5061 Timeout=2014-12-03 15:19:29 Pending lifetime=0 [...] ----------------------------- According to netstat, the server had lots of CLOSE_WAIT sockets: ----------------------------- tcp 361 0 sip_test_ip:5061 67.21.5.36:32969 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:36210 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:17264 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:10884 CLOSE_WAIT tcp 464 0 sip_test_ip:5060 172.56.38.226:65288 ESTABLISHED tcp 361 0 sip_test_ip:5061 67.21.5.36:56345 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:46915 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:62188 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:28660 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:62848 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:16914 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:37157 CLOSE_WAIT tcp 361 0 sip_test_ip:5061 67.21.5.36:27378 CLOSE_WAIT ------------------------------- I think something happened with the first TCP connection because it had "strange" State = 18446744073709551615 So what is "State" mean? -- NguyenVD
