Jvisualvm: Stuck on screen "Loading dump heap ..."

Question

I am using jdk64 and my java version is "1.6.0_24". My tomcat works with -Xmx7196m and jvisualvm works with -J-Xms2048m -J-Xmx3072m. I took a bunch of heaps of my tomcat java process and my file size .hprofis about 5.5 GB. When I try to open this heap heap, it just got stuck on the screen Loading Heap Dump....

I also looked at the consumption of the VisualVM heap while it tries to open the heap heap, but it's approximately 500 MB.

NOTE: I looked at jvisualvm: it’s stuck on the “Loading dump heap” screen , but it is different and does not concern my question.

Answer 1

These symptoms also occurred when I tried to load a large heap heap and had a small disk space (I assume that for temporary use of files visually vm) works on a Mac. After freeing up disk space, the file loaded.

Answer 2

You can try a few things:

• Java VisualVM bundled with JDK 1.6.0_24 - several years. Try using the latest version (1.3.7) from http://visualvm.java.net .
• VisualVM uses memory mapped files, so you don't need to run its 3G heap. I would start with a heap of 1G. How much free memory does your OS have when trying to open a heap dump?
