Analyze Memory on BlackBerry

[ Edited ]


we have self written Java programs on BlackjBerry 8800 with Firmware 4.5.

The BlackBerry runs out of memory.

Is there any chance to identify the application that caused the problem?
Is there a chance to read the persistent memory and get the size stored under different IDs?

Regards Juergen

Re: Analyze Memory on BlackBerry

It would surprise me if you had run out of persistent memory, typically in situations like this it is some kind of recursive call or a serious memory leak.


I would recommend that you review the following videos, I strongly recommend the Garbage collection one because it will tell you all about it and also tell you how to use the JDE profiler, which is the tool that you need to use.  There is information on running it in the Help too, so I won't put any details in here.


Garbage Collection



Low Memory Handler



Review these, you should get some hints, but do come back to us if you can't sort it out yourself.
