Can't open HPROF file with Eclipse Memory Analyzer
10,211
Solution 1
I had the same issue. Adding the flag "format=b" fixed the issue. Apparently, Memory Analyzer can only read binary files.

If you're using a java service wrapper, most likely the JVM got killed before it could finish writing the heap dump. You may want to set a property for the service wrapper that will give the vm more time to complete the heap dump.

Eclipse Memory Analyzer prompts me only with this message: "Invalid HPROF file header".
Stack dump:
java.io.IOException: Invalid HPROF file header. at org.eclipse.mat.hprof.AbstractParser.readVersion(AbstractParser.java:135) at org.eclipse.mat.hprof.Pass1Parser.read(Pass1Parser.java:69) at org.eclipse.mat.hprof.HprofIndexBuilder.fill(HprofIndexBuilder.java:65) at org.eclipse.mat.parser.internal.SnapshotFactoryImpl.parse(SnapshotFactoryImpl.java:184) at org.eclipse.mat.parser.internal.SnapshotFactoryImpl.openSnapshot(SnapshotFactoryImpl.java:102) at org.eclipse.mat.snapshot.SnapshotFactory.openSnapshot(SnapshotFactory.java:114) at org.eclipse.mat.snapshot.SnapshotFactory.openSnapshot(SnapshotFactory.java:94) at org.eclipse.mat.ui.snapshot.ParseHeapDumpJob.run(ParseHeapDumpJob.java:54) at org.eclipse.core.internal.jobs.Worker.run(Worker.java:55)
The HPROF file was made on a Linux machine.
HAT doesn't work and the IBM HeapAnalyzer is to complicated, but did work.
What can I do to make it work?
