I have a problem with filebeat that it reads the file while the file is being overwritten by another process. This problem result in loading/reading some junk entries by Filebeat.  
My current configuration is :  
filebeat.inputs:

- type: log  
enabled: true  
paths:

filebeat.config.modules:  
path: ${path.config}/modules.d/\*.yml

reload.enabled: false

setup.template.name: "sys\_username\_mapping"  
setup.template.pattern: "sys\_username\_map\*"

json.overwrite\_keys: true

output.logstash:  
hosts: ["10.129.212.45:5043"]

logging.level: info

Here same file "filetoload" is getting updated(overwritten) once per day at 1:00 PM and the path is on NFS. So I want that filebeat should read/load the file only if it is not being overwritten by any other process  
Please suggest
