Edit :
Some steps that have been tried to resolve this issue when parallel SSH hook
operators are running
1. Increase MaxSessions and MaxStartups in sshd_config file
2. provide banner timeout, connection timeout, command timeout values in SSH
operator
conn_timeout = 120,
cmd_timeout = 120,
banner_timeout = 90.0
3. Expire_time value in ComputeEngineSSH hook operator ( expire_time = 120)
There are no errors observed in auth.log but the Airflow DAGs have similar
issues as described in
https://github.com/paramiko/paramiko/issues/1135
Is there a need to provide disabled algorithms in the operator with Paramiko
>=2.9 because that seems to be one of the solutions listed
