too many open files with Lucene

ncg
Hello,

Since the migration from 4.1.3 to 4.4, there are "too many open files" alerts in Tomcat (release 5.5).

I changed limit from 1024 (default value) to 4096 but the problem is not solved.

It seems there are many open files used by lucene :

Total tomcat open files :
>/usr/sbin/lsof |grep java | wc -l
3318

Lucene open files :
>/usr/sbin/lsof |grep java | grep "/xem/data" |  wc -l
2524

Lucene "deleted" open files :
>/usr/sbin/lsof |grep java | grep "/xem/data" | grep deleted |  wc -l
1663

This behavior is new with 4.4. There is a known problem with Lucene ?

Thank you

Ncg

Thanks
