I’ve been facing some annoying OutOfMemoryErrors , even after making sure that all my Bitmaps are properly scaled etc. In fact, the issue doesn’t seem to be related to Bitmaps at all, but I may be wrong. For testing and error-isolation purposes, I’ve been switching between two activities (let’s call them Main and List) using my Navigation Drawer (not using the back button). I can see in the DDMS that the allocated memory increases around 180 KB every time I return. I’ve done memory dumps and used eclipse MAT to analyze 3 different points in time: I suspect a memory leak but I can’t really find

The Eclipse Memory Analyser docs say it can open IBM portable heap dump files (*.phd): http://help.eclipse.org/luna/index.jsp?topic=/org.eclipse.mat.ui.help/welcome.html However, when I try to open one I get and error: 'heapdump.xxx.phd'. Check the error log for further details. Not a HPROF heap dump (java.io.IOException) Not a HPROF heap dump I've tried both menu options (File > Open Heap Dump) and (File > Open File) You have to install DTJF in order to read IBM files. http://wiki.eclipse.org/MemoryAnalyzer#System_Dumps_and_Heap_Dumps_from_IBM_Virtual_Machines Eclipse download site is at the

I have some issues with running Eclipse memory analyzer on my laptop. This happen when i have just downloaded(from the place ) and executed application: And i can't figure out what is the cause of problem. Can someone help me??? Move mat.app to ./Applications solve my problems It looks like a permission problem with the default directory. From this discussion : Memory Analyzer » Setting up workspace directory? . It is indicated that you should edit your MemoryAnalyzer.ini file, and add those lines ( on two separate lines, and before the vm arguments ), replacing the second with the path where

I was trying to investigate java.lang.OutOfMemoryError: GC limit exceeded which occurs at high load of our web app deployed in tomcat. Heap size was set to 8GB ( -Xms2048m -Xmx8192m ) At some point in time our application become unresponsive due to GC activity overhead. I could see in logs that Full GC was occurring multiple times in a row. So I took heap dump with following command ( jmap -F -dump:format=b,file=/root/dump2.hprof 4963 ). File containing dump was 9GB in size. After dump was taken (app was frozen for about 45minutes), multiple full GCs occured till OutOfMemoryError was thrown.

I'm analyzing memory usage of my Android app with help of Eclipse Memory Analyzer (also known as MAT). Sometimes I can find strange instances of android.graphics.Bitmap class, utilizing big portion of heap. Problem is what I can't find source of this bitmaps, no filename , no resourceID , nothing. All information what I can find for bitmap is following: There is a field mBuffer with array of image pixels, I assume. But it's in some internal Android format, not PNG. Question : how can I view image represented by this bitmap from memory dump? HitOdessit I have found a way to view such bitmaps:
