Omap3530 Memory Usage

msj
Intellectual 830 points

Other Parts Discussed in Thread: OMAP3530

I have been having random glibc errors:

*** glibc detected *** ./cap_encode_omap3530.x470MV: free(): invalid next size (
normal): 0x000eae90 ***
or
*** glibc detected ***: double free or corruption ( !prev): 0x000eafa0 ***

 

which is suspiciously like this thread:

http://e2e.ti.com/forums/p/2394/9226.aspx#9226

I also noticed by utilizing the top utility that this application is using a lot of memory.(94% +)

 

Does anyone have any ideas about tracking these kind of errors down?

 

msj

    This sounds like your application is trying to free some memory that has already been deallocated.  You could try to use a debugger like ddd to pinpoint where in your code this may be occuring.  For instructions on using ddd, look here http://www.ti.com/litv/pdf/spraap9.

    Without knowing more about your application, it's hard to say what's causing the high memory usage, but this could also be an issue with incorrect allocation of memory.
