File Permission denied: Filebeat 6.6.0 on Windows

Hi All,

I know that the filebeat does not require an exclusive lock on the file, but I faced with a not clear behavior on a windows machine with running filebeat as a windows service.

I have a log file (SomeTextFile.log) which is created by python process on the local drive. The python process is terminated after. Then in a few milliseconds, the new process tries to append something to the file, but it gets the permission denied the exception on opening the file.

PS D:\Handle> whoami
test
PS D:\Handle> .\handle64.exe -u SomeTextFile.log
filebeat.exe       pid: 2184   type: File          VM-CI\test           320: D:\data\log\SomeTextFile.log
PS D:\Handle> python -c "open('D:\data\log\SomeTextFile.log', 'a')"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
IOError: [Errno 13] Permission denied: 'D:\\data\\log\\SomeTextFile.log'
PS D:\Handle> .\handle64.exe -u SomeTextFile.log
filebeat.exe       pid: 2184   type: File          VM-CI\test           320: D:\data\log\SomeTextFile.log

Any hints on how to understand this behaviour would be very valuable, thanks!
