I am hosting several Java Web apps on Tomcat and periodically (about once a month) the server crashes with OutOfMemory exceptions. I allocate 2Gig (2048M) to Tomcat.
Sooo.... I am now trying to analyze the HeapDump (.phd) file that generated. I found he396 and I am trying to use it to do this. I give it 3000m (java -Xmx3000m -jar he396.jar) and it gets about 95% finished (according to the Overall progress bar) and then I get an out of memory exception using the tool... (sorry for the formatting below)

What can I do to read this file? I have tried as much as -Xmx3500m and it still does not finish. The actual heap dump file is about 450MB.
try this code below: i believe it will be of great help to you. I almost had the same config like yours but with this piece of code the HeapAnalyser managed to reach 100%.
