heap-dump

Using memory analyzer from eclipse ide (kepler), I'm trying to acquire heap dump from a locally running VM while an program is running, however acquire heap dump dialog does not list any pid to select. I try to configure hdrof jmap dump provider with -jdkhome C:\Program Files\Java\jdk1.8.0_05\bin but nothing happens. Any solution. Thanks. remove bin from your path , It should be -jdkhome C:\Program Files\Java\jdk1.8.0_05 来源： https://stackoverflow.com/questions/24433668/memory-analysis-from-eclipse-ide-does-not-list-any-local-process-id-when-acquire

I have got a large (5GB) hprof dump, created by application when OutOfMemoryError occurred. (Using XX: HeapDumpOnOutOfMemoryError ). Unfortunately there are no logs collected when this error happened. Re-creating this will take couple of hours. I was hoping if some tools could show the exception stack trace or all threads stacks etc from hprof. I am currently using MAT , could not see a way to get thread information. Which tool I could use? (I am not sure if hprof file has information about thread/location of call when OOM occurred). ( I do know to how to take thread dump in normal cases. The

We are working over our client's production server heap to detect and solve memory leaks. For this we are using jmap periodically to collect the necessary information. But last week we couldn't take the dump, because it triggered a EOF error and shutdown the Tomcat instance. I searched on the internet but couldn't find any concrete information about this error.

You can make heapdump and store on the remote machine. To analyze heapdumps can advice you: MAT . Very powerful tool which allow you to

Can someone tell me what does bold, blue one and red one positions in HPROF Viewer in Android Studio means exactly ? I ask about one in Reference Tree panel. Best regards. FuegoFro I can't find any documentation on this, but from looking through a few heap dumps this is what they seem to be: blue - The closest dominator of the instance selected in the top-right pane. bold - A GC root, eg an instance with depth 0 that should not be collected. This answer has more information on what a GC root is, and this answer lists the types of things that are roots. red - I haven't actually seen these, but
