Out of memory..

[Altera_Forum]

I'm running an application that runs with 16 threads ( 17 if you count main()) on uCLIunx Nios II with 32 MB SDRAM. After it runs a while (for almost 1/2 hour), suddenly the OS does this:

Problem stemmed from the fact that the two NIOS processors on the board had mismatched kernel and or rootfs. 

 Wow, weird problem requires weird solution.
