Hello there
I need some help with a odd behave with Lucene since version 2.9
I have a project with Lucene 2.41 that runs fine with 600k document where I use
two index folder to separate two set of index, one primary and another one
secondary, this allow me to switch the indexreader/indexsearcher by the time I
want to build a fresh index and also keep a safe copy of it,
While I am using Lucene 2.4.1 I have no problem with my application regarding
have a web application hitting many time the searcher, which is shared, when I
have to switch the index, I do check which one is stale and then close the old
one and open the new one, even having many threads into my container, it can
safely close and open this, without having any problem.
This days, since version 3 arrives, I've being trying to upgrade my application
for all matters, by the end of this, everything seems OK, BUT DID NOT,
I used JMeter to put it to burn, then I got this :

so, somehow my container keeps old indexsearcher/indexreader opened, even the
files no longer exists, that making it to reach max open files from the System,
and you know what comes next.
Even look like complex, for the time it grown the many file opened is invert
when use Lucene 2.4.1, which manage and close all old indexsearcher/indexreader
and keeping clean the opened files from lsof command from linux, where I run
this application
As I can not change my entire application to use Solr, which seems to have a
good approach, and I also can not walk back to Lucene 2.4.1 and let it there
forever, I ask for help here.
If anyone from there can help me, please let me know
Best regards and very thanks in advanced
Wilson
