Hello, We are using the OpenSIPS server with MSRPRelay and we see this strange behaviour. Usually, we can successfully create and destroy MSRP streams but at some point we try to create multiple MSRP sessions almost smiultaneously and some of them fail with a ³Internal server error² response. In the server logs we have these messages: Jan 31 08:21:27 /sbin/opensips[2157]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed Jan 31 08:21:27 /sbin/opensips[2157]: ERROR:core:tcp_send: connect failed Jan 31 08:21:27 /sbin/opensips[2157]: ERROR:tm:msg_send: tcp_send failed Jan 31 08:21:27 /sbin/opensips[2157]: ERROR:tm:t_forward_nonack: sending request failed Jan 31 08:21:27 /sbin/opensips[2163]: ERROR:core:tcp_blocking_connect: poll error: flags 1c Jan 31 08:21:27 /sbin/opensips[2163]: ERROR:core:tcp_blocking_connect: failed to retrieve SO_ERROR (111) Connection refused Jan 31 08:21:27 /sbin/opensips[2163]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed Jan 31 08:21:27 /sbin/opensips[2163]: ERROR:core:tcp_send: connect failed Jan 31 08:21:27 /sbin/opensips[2163]: ERROR:tm:msg_send: tcp_send failed Jan 31 08:21:27 /sbin/opensips[2163]: ERROR:tm:t_forward_nonack: sending request failed Jan 31 08:21:27 /sbin/opensips[2161]: ERROR:core:tcp_blocking_connect: poll error: flags 1c Jan 31 08:21:27 /sbin/opensips[2161]: ERROR:core:tcp_blocking_connect: failed to retrieve SO_ERROR (111) Connection refused Jan 31 08:21:27 /sbin/opensips[2161]: ERROR:core:tcpconn_connect: tcp_blocking_connect failed Jan 31 08:21:27 /sbin/opensips[2161]: ERROR:core:tcp_send: connect failed Jan 31 08:21:27 /sbin/opensips[2161]: ERROR:tm:msg_send: tcp_send failed Jan 30 12:00:44 /sbin/opensips[2157]: ERROR:tm:t_forward_nonack: sending request failed Jan 30 12:00:49 /sbin/opensips[2159]: ERROR:core:_tls_read: SYSCALL error -> (0) <Success> Jan 30 12:00:49 /sbin/opensips[2159]: ERROR:core:_tls_read: something wrong in SSL: 5 Jan 30 12:00:49 /sbin/opensips[2159]: ERROR:core:tcp_read_req: failed to read
On the server side we have OpenSIPS server working over TLS, also we have MSRPRelay working on TLS. On the client side we are using sipsimple. Thank you, -- Mihai Richard
