Subject Re: JVM Heap utilization & Memory leaks with Solr
Date Thu, 13 Aug 2009 05:24:45 GMT
*You should try to generate heap dumps and analyze the heap using a tool
like the Eclipse Memory Analyzer. Maybe it helps spotting a group of
objects holding a large amount of memory*

The tool that I used also allows to capture heap snap shots. Eclipse had a
lot of pre-requisites. You need to apply some three or five patches before
you can start using it........ My observations with this tool were that some
Hashmaps were taking up a lot of space. Although I could not pin it down to
the exact HashMap. These would either be weblogic's or Solr's.... I will
anyway give eclipse's a try and see how it goes. Thanks for your input.
