[BUG]: <title>The server closing the TCP connection when stopping all services.

[AGN-2022]

vSomeip Version

v3.4.10

Boost Version

1.59

Environment

Ubuntu 20.04

Describe the bug

1. Server Offering services.
2. Client initiates TCP connection by sending [SYN]. [by 3-way handshake connection established]
3. Client subscribes to a particular Event group offered by Server.
4. Server sends ACK to client.
5. Client calls method "SuspendInterface" to Server. [Intended to trigger Stop Offer from Server]
6. Server sends Stop Offer Service Entry.
7. Server initiates TCP connection close request by sending [FIN, ACK] to Client.

The TCP connection close request should not get triggered by Server, in this case this is the issue from VSOME/IP stack.

I observed the same behavior in 3.1.20.3 and 3.4.10.

Attached pcap log and Routing manager terminal log: TCP_close_issue_pcap_RM_logs.zip

Reproduction Steps

Steps 3 to 5 can reproduce the issue.

Expected behaviour

The server shall not stop the TCP connection when stopping all services.
Let the client to process control data & shutdown the connection by itself.
