New issue 108 by [email protected]: TCP/TLS channel resend problem
http://code.google.com/p/jain-sip/issues/detail?id=108
What steps will reproduce the problem?
1. Use sip client with tcp/tls connection when client is behind nat.
2. Send keepalive or any other data from client periodically to allow
channel reestablishment ( in my case it 2 minutes )
3.clear nat table on nat machine ( can be done by 3G network providers or
any router when no packet received after some time )
4) Send message from server to client,wait 30 seconds.
What is the expected output? What do you see instead?
Client transaction should expire and cancel sending the packet to client.
Instead transaction is expired but packet is resent as soon as connection
to client is recovered ( due to keepalive from client side )
What version of the product are you using? On what operating system?
latest nio
Please provide any additional information below.
message is sent from stack to tcp buffer , which keeps it all the time if
it has enough space.by default its 512KB.
Therefore stack puts the message into buffer , then transaction is
expired , but message remains in buffer and therefore resent.
Stack does not tries to remove the request from buffer.
