I have a very large Heap Dump (.hprof) file (16GB). When I try to open it in Visual Vm,the VM just hangs. I tried to open it in JProfiler. Jprofiler gave me a Out Of Memory error. Below is how my jprofiler.vmoptions looks like. What should be the ideal configuration, I should be using in order to open the HPROF without issues? I am running on a 8GB Linux box.
-Xmx1536m -XX:MaxPermSize=128m -Xss2m
JProfiler 8.1 will be able to open much larger HPROF files without tuning the -Xmx VM parameter. To get a pre-release, please contact support@ej-technologies.
