I'm getting the following exception when running Infinispan testsuite on Solaris with NFS (Network File System):

{code}

More FileCacheStore tests fail because of this problem: https://hudson.qa.jboss.com/hudson/view/EDG6/view/EDG-QE/job/edg-60-community-testsuite-solaris/jdk=java16_default,label=sol10_x86_64/16/testReport/org.infinispan.loaders.file/

I was not sure what this means and found this explanation on the internet:

The .nfsxxxx files are used by NFS clients to manage
the deletion of open files. If an open file is deleted
then the client renames it to .nfsxxxx. If the last
open to this file is closed then the client should
send a request to remove it. If the client crashes
before it can clean up then you'll be left with these
files. 

I think Infinispan should count with using NFS ans ignore the files with .nsf prefix when loading all buckets into memory.
