IOS_XR send_command OSError: Search pattern never detected with Netmiko 3.3/3.4

[ebinachan]

Hi Kirk,

First of all, great work on Netmiko, I've been using it a lot.
Most of my scripts are based on version 2.4.2 on IOS and IOS_XR, and they work great.
I noticed that versions 3.3.0 and 3.4.0 seem to "hang up" when running send_command on XR routers with hundreds/thousands subinterfaces or huge configs:

  File "/home/me/.local/lib/python3.6/site-packages/netmiko/utilities.py", line 500, in wrapper_decorator
    return func(self, *args, **kwargs)
  File "/home/me/.local/lib/python3.6/site-packages/netmiko/base_connection.py", line 1537, in send_command
    search_pattern
OSError: Search pattern never detected in send_command: RP\/0\/RSP0\/CPU0\:THISROUTER\#

show interfaces description | include "(TAG1)|(TAG2)" 

Am I doing something wrong or should I open a new issue?

Thanks,
Ebina

Increased "global_delay_factor": 2, now the script will successfully complete.
