My application also meet this problem last year and I researched on the code
and found the reason.
The whole process is as follow:
1. When using NRTCachingDirectory, it will use RAMDirectory as cache and
MMapDirectory as delegate. The new segment will be created in the process of
flush or merge

Hi,
how does your configuration for NRTCaching directory looks like. There are 2
constructor params, one of the maxMergeSizeMB the other one is maxCac
Hi,
how does your configuration for NRTCaching directory looks like. There are 2
constructor params, one of the maxMergeSizeMB the other one is maxCachedMB. If
you correctly close (or release in case of ReaderManager/SearcherManager) all
indexes, this should limit the memory use.
There is no
use MMapDirectory instead
of NRTCachingDirectory?
Thanks & Best Regards!

Could it be that you forgot to close older IndexReaders after getting a new NRT
one? This would be a huge memory leak.
I recommend to use SearcherManager to handle real time reopen correctly.

Hi, all
I fould that the memory consumption of my lucene server is abnormal, and
“jmap -histo ${pid}” show that the class of byte[] consume almost all of the
memory. Is there memory leak in my app? Why so many byte[] instances?
The following is the top output of jmap:
