Hilarious. –Doc Jun 15 at 20:46 add a comment| 8 Answers 8 active oldest votes up vote 39 down vote The problem is that Eclipse Memory Analyser does not have enough heap space to open the Heap dump file. You can solve the problem as follows: open the MemoryAnalyzer.ini file change the default -Xmx1024m to a larger size share|improve this answer edited Dec 30 '14 at 13:23 ICR 8,90623266 answered Mar 22 '12 at 10:15 codeisee 48749 thanks for your reply,but i can't find MemoryAnalyzer.ini file,where is the location ? –Gavin Mar 22 '12 at 10:49 1 it locates in the default dir.but if you are using a

I tried increasing the size of heap in MemoryAnalyzer.ini to 80% of the file size. Still no luck. I also tried using jhat and yourKit. Not helping. Someone kindly help me in this case. java heap-dump share|improve this question asked Aug 13 '14 at 10:14 Rajesh 264210 add a comment| 1 Answer 1 active oldest votes up vote an internal error 3 down vote accepted I am little confuse on what you tried increasing the size of heap in MemoryAnalyzer.ini to 80% of the file size Solution 1: I know you already tried but 80% is little confusing 1.open the MemoryAnalyzer.ini file ; 2.change the default -Xmx1024m to a larger size. Solution 2: If you have local setup of your code, add some debug points and take heap dumps at runtime on every debug break point (which will divide your big size heap dump file into smaller size file. You will solve size issue and it will be easy to get to root cause faster) share|improve this answer answered Aug 13 '14 at 14:21 Mind Peace 532420 1 Hi thanks for your reply. I read in some site that the size to be set in the memory analyzer.inf should be 80% of dump file to be read. That's what i meant. Anyhow that didn't work. Your second solution is a mind opener. i'll try and let you know. –Rajesh Aug 16 '14 at 3:32 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the priv
