packet_write_wait connection to unknown port 65535 broken pipe

[Ramnikov]

When executing the long-running command like DB2 and InfoSphere installation ssh connection is breaking.
I have tried to add to ansible.cfg following line:

ssh_args = -o ServerAliveInterval=50

Unfortunately, it is not resolving the issue. This happens on RHEL 7 zLinux environment.

Did you have this issue?

[Ramnikov]

To solve the issue we need to update the ssh configuration.
On the Node that Ansible run we need to create a config file

touch ~/.ssh/config

In the config file add following Entry:

Host *
TCPKeepAlive yes
ServerAliveInterval 120
ServerAliveCountMax 5

Aftre the file was edited run the ssh restrat command:

systemctl restart ssh
