[ERROR][o.a.p.p.f.FileSystemFontProvider] Error accessing the file system

Elastic Stack Elasticsearch
1

version[5.2.2], pid[1472], build[f9d9b74/2017-02-24T17:26:45.835Z], OS[Windows Server 2012 R2/6.3/amd64], JVM[Oracle Corporation/Java HotSpot(TM) 64-Bit Server VM/1.8.0_66/25.66-b17]

I noticed that ES is spamming errors in our production Environment and I am not sure what causes it, nor what problems (if any) our end users experience because of it. I searched the forum for topics similar to mine but could not find any solution or clues. Help is much appreciated. Posting the error message below.

Could you upgrade your elasticsearch version to at least the latest 5.6 version or better 6.4?
IIRC this has been fixed.

May be more details on

Although it can be something else. In which case, it would be good if you can reproduce the problem on 6.4.2 and share within a new issue the file which is causing that.
