The garbage collector in Java 8 may have different behavior. This may cause
issues if you have buggy code that does not close indexreaders open in parallel
to indexing. If it relies on Garbage Collector to close accidentally open
files, that won't work anymore on Java 8. The reason for this migh

No code changes between running in Java 6 and Java 8. The same code still
runs successfully with Java 6 while is failing with Java 8.

Did you make any changes to your code between running on java 6 and 8?
The java file API has changed considerably since java 8.
If you -have- rewritten some of the file handling code in your indexing
process, make sure to explicitly close the streams you create, or use

Hi Dean,
can you describe your problem more in detail?
Some time ago I used Lucene to Index 50-Millions of medium-sized-text
documents. But I didn't run into a problem having 1000th of open files.
Maybe you can explain, what are you trying to do?

No. Certainly not for lucene 3.0.3 on linux anyway.
As someone has already suggested, run lsof to see which files your
process has open. Maybe you aren't closing the source documents.

Ask your sys admin to increase the os max open file limit

You are probably not closing all your searchers properly. What

After a closer look, I forgot to mention a major clue : it's also the
first time we use NRT.
I thought IW.getReader() would return a pooled NRT and in fact it
returns always a new IR. This should explain the Too many opened files
exception. After each addDocument(doc) I prepare a reader with

I just added some .close() calls to a few places where I kept file

We do optimize() after indexWrite.
The maximum open file allowed is 2,000. Is this normal, too small? What is your

How many files are in the index directory?
If your index is not optimized, try optimizing it first?
What's the max number of open files (ulimit -a)? If it looks low,
increase it.
It looks like you have 20+ fields. How many fields have you got? (just
curious)

Hi, Dan,
I think the problem you mentioned is the one that has been discussed
lot of times in this mailing list.
Bottomline is that you'd better use the compound file format to store
indexes. I am not sure Lucene 1.3 has that available, but, if
possible, can you upgrade to lucene 1.4.3?
Cheers,
