issue with Cisco ios-config

Hi,

I am trying to load a pretty long access-list to a Catalyst 3850 using Ansible ios-config module with the src option.

  • name: copy to the acl to target switches
    ios_template:
    src:a_test_acl.txt

However it only works with the list with less than 378 entries. I can confirm that there is no problem with the switching accept long access list.
I also tried the ios_config module.
