thanks Uwe for reply. we are indexing data in a cluster where there are
many mount points so it is possible that one them has issue or slowness
when this check first tried but now when i execute "mount" it is
responding all the mount points.
I was wondering is there any configuration to skip this SSD check?

Hi,
to figure out if you system is using an SSD drive for the index
directory, the merge scheduler has to get the underlying mount point
of the index directory. As there is no direct lookup for that, it
needs to list all mount points in the system with a Java7 FS function.
And that seems to hang for some reason. Could it be that you have a
mount (like NFS or CIFS) that no longer responds?
Just list all with “cat /proc/mounts” or the “mount” command and check
if any of them is stuck or no longer responding.

*Subject:* stucked indexing process
Hi all,
we are having an issue in our indexing pipeline time to time our
indexing process are stucked. Following text&picture is from jvisualvm
and it seems process is waiting at
sun.nio.fs.UnixFileSystem$FileStoreIterator.hasNext() method all the
time. we are using lucene 5.4.1 and java 1.8.0_65-b17.
what can be the reason of this?
Many Thanks
Tamer
