Logstash Data path and NFS

We have seen cases where NFS and the logstash data folder don't play very well together. Do we need to recommend not to use NFS with logstash data path?

Is there any incompatibility (in the code) between Logstash and NFS?

Begin by locating Logstash’s data-path handling and reviewing the reported NFS cases. Check whether the repository contains a reproducible incompatibility; done means documenting a supported recommendation about using NFS with the data path, backed by confirmed behavior or a confirmed absence of code incompatibility.
