I switched from Lucene 2.4.0 to the latest 2.9.0 version and got too many
files open within a few hours from my indexing process. Our indexing Java
process adds about 2000 documents/minute.
The IndexWriter (iw) has the following settings:
iw.setMaxFieldLength(1024*1024*1024); // 1G as maximum terms.
iw.setMergeFactor(10);
iw.setMaxMergeDocs(100000);
iw.setMaxBufferedDocs(1000);
iw.setRAMBufferSizeMB(128);
iw.setUseCompoundFile(true);
The 'lsof' result shows rapidly growing number of open files in 'deleted'
state. Counting the number of these:
[server-1]#date
Sun Oct 18 11:02:37 EDT 2009
[server-1]# lsof -p 19606 |grep deleted |wc -l
3187
[server-1]# date
Sun Oct 18 11:07:29 EDT 2009
[server-1]# lsof -p 19606 |grep deleted |wc -l
3912
Here is a sample of those open files left behind in 'deleted' state:
