Netmiko & Paramiko Tracebacks net_connect.send_config_set(lines)

Hello,

Getting the below Error , trying to configure multiple switches but most the script fails after configuring only 1 switch.
And sometimes it doesn't configure at all throws the tracebacks when running the script.
Look at it looks like some timeout issue.

Here is the script -
auritro@auritro-python:~$ cat netmiko3.py
#!/usr/bin/env python3

from netmiko import ConnectHandler

iosv_l2_s1 = {
'device_type': 'cisco_ios',
'ip': '192.168.122.71',
'username': 'auritro',
'password': 'auritro',
}

iosv_l2_s2 = {
'device_type': 'cisco_ios',
'ip': '192.168.122.72',
'username': 'auritro',
'password': 'auritro',
}

iosv_l2_s3 = {
'device_type': 'cisco_ios',
'ip': '192.168.122.73',
'username': 'auritro',
'password': 'auritro',
}

iosv_l2_s4 = {
'device_type': 'cisco_ios',
'ip': '192.168.122.74',
'username': 'auritro',
'password': 'auritro',
}

iosv_l2_s5 = {
'device_type': 'cisco_ios',
'ip': '192.168.122.75',
'username': 'auritro',
'password': 'auritro',
}

with open('iosv_l2_config') as f:
lines = f.read().splitlines()
print(lines)

all_devices = [iosv_l2_s5, iosv_l2_s4, iosv_l2_s3, iosv_l2_s2, iosv_l2_s1]

for devices in all_devices:
net_connect = ConnectHandler(**devices)
output = net_connect.send_config_set(lines)
print(output)

Kindly provide your guidance.

Start with the reported netmiko3.py call to send_config_set(lines), then compare the traceback paths in paramiko/channel.py and paramiko/base_connection.py. Reproduce the timeout with the supplied multi-device script and determine whether the result identifies a Paramiko defect; a complete report would need a confirmed cause and a specific change or test target.
