Subject Issue of LUCENENET-106 memory leak
Date Tue, 23 Sep 2008 04:01:49 GMT
Hi all,
It seems that issue,
not fully fixed.
My observation of memory usage still get continuous increasing.
By using two profilers(YourKits profiler and MS .Net CLR Profiler), I found
that "Lucene.Net.Index.SegmentReader/Norm" and "Lucene.Net.Index.FieldInfo"
will be increased 41 object(both these two classes) instances when search
index(yes, sort is involved).
These increased object instances won't be grabage-collected and as result my
system will soon reached memory limitation and fire CLR recycle whole

My Lucene.Net version is and source is grab from SVN.
Please help on this.

Best regards,
