java - jvisualvm: Stuck on “Loading Heap Dump...” screen -


i using jdk64 , java version "1.6.0_24". tomcat running -xmx7196m, , jvisualvm running -j-xms2048m -j-xmx3072m. took heap dump of tomcat java process , size of .hprof file around 5.5 gb. when try open heap dump, stuck on loading heap dump... screen.

i looked @ heap consumption of visualvm while trying open heap dump, goes around 500mb only.

note: did @ jvisualvm: stuck on “loading heap dump” screen question different , not address question.

you can try several things:

  1. java visualvm in bundled jdk 1.6.0_24 several years old. try use latest version (1.3.7) http://visualvm.java.net.
  2. visualvm uses memory-mapped files don't need start 3g heap. start 1g heap. how free memory have os when try open heap dump?
  3. there should progress bar in right corner of visualvm, show progress of loading of heap. should give clue how long can take.
