Hey there, I have posted about this problem before but I think I didn't
explain mysql very well.
I'll try to explain my problem inside the context:
I get ids from a database and I look for the documents in an index that
correspon to each id. There is just one match for every id. One I have the
docuement, I have to modify some fields. What I do is to create a new doc,
copy the fields of the old doc doing the modifications, delete the old doc
from the index and add the new.
I have to do it for about 5.000 documents.
My problem is that when I ejecute the app it starts increasing the memory
use until 700Mb or even more.
I have realized that the memory leak apperars when getting the docuements.
I leave here the piece of code I use to do that... any advice would be
really helpful coz it's driving me mad.
private Document getDocumentData(String id) {
IndexSearcher searcher = null ;
IndexReader reader = null;
Document doc = null ;
TermDocs td = null;
try {
searcher = new IndexSearcher(path_my_index) ;
reader=searcher.getIndexReader();
td=reader.termDocs(new Term(GlobalFields.ID,id)) ;
if(td.next())
{
doc = reader.document(td.doc()) ;
}
if(td != null)
{
td.close() ;
}
td=null;
} catch (Exception ex) {
logger.error("Troubles geting data: " + ex.getMessage()) ;
logger.error("Stack: " + ErrorStack.getError(ex)) ;
} finally {
if(searcher != null) {
try {
reader.close() ;
searcher.close() ;
reader = null ;
searcher = null ;
} catch(Exception e){} ;
reader = null ;
searcher = null ;
}
}
return doc ;
}
This functions is called for every doc which I have to get the information
PD: If I call manually the garbage collector at the end of the function the
memory leak never apears... but the app runs really slow!!
Thanks in advanced
Marc
