Out of memory issue

[bri...@gmail.com]

Helllo,

I came across the out of memory issue in my web application. We have created the heap dump on OOM. After analyzing the heap dump, I figured out that there are 57 objects of SearchIndexManager.java and 163 object of BoboIndexReader.java. Which are root cause of the OOM.

While debugging the source code, I figured out that SearchIndexManager object has been created when Zoiesystem object is created. Which we are creating only once at the time of system start up. so wondering how come it creates so many objects ?

Label	Number Of Objects	Used Heap Size	Retained Heap Size	Retained Heap, %
proj.zoie.impl.indexing.internal.SearchIndexManager	57	4,104	988,058,840	43.89%
com.browseengine.bobo.api.BoboIndexReader	163	20,864	814,357,896	36.18%
proj.zoie.impl.indexing.internal.IndexReaderDispenser$InternalIndexReader	5	640	171,706,296	7.63%

Any help is greatly appreciated.

Hello,

I have observed that this issue is resolved in Zoie 3.2. For zoie 2.0. So Ideal approach is to upgrade the library to latest version. however after analysis of Heap dump, GC roots and debugging of source code zoie 3.2 jar source. I have modified the shutdown method of Zoiesystem.java.

OptimizeScheduler scheduler = _diskLoader.getOptimizeScheduler();

scheduler.shutdown() 

It fixes the memory leaks. 

Best Regards,

Brij

Hello John,

Thanks for considering this fix to merge. however to be honest, I don't know how to create fork from repository. Currently I have attached source code to my eclipse workspace and make the changes.

I would appreciate if you explain or provide some guideline to fork the repository and pull request for it ?

Best Regards,

Brij
