Subject stucked indexing process
Date Wed, 12 Jul 2017 10:29:12 GMT
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
