I have java application that is crashing while in production. It doesn't do so in dev/QA. The jvm is creating a .mdmp file and a text file. How do I analyze the binary dump file? I googled but had no luck. We are using bea jrockit jvm 1.5 R27.

MDMP files are saved as binary files to disc and can be opened with Microsoft Visual Studio debugger.
Click Start, and then click Control Panel. Double-click System, and then click Advanced system settings. Click the Advanced tab, and then click Settings under Startup and Recovery. In the Write debugging information list, click Small memory dump (256k).
The .mdmp file is a Windows MiniDump file that you can only read with a debugger (like WinDbg). Typically you need the sources of the crashed application to really get some information out of the dump. So in your case you can't do much but contacting JRockit support.
Here a link to the Orace JRockit information about JVM crahes.
