Why system panic after sometimes?

[Dross Zhou]

Hello all,
This question has bothered me,I use linux-2.4.4 (
downloaded from denx.de and porting to our borad
MPC850+4Mflash+32Mram+USB).We run a server application
in borad,but after sometimes such as about a day or
even several hours ,system will panic. I check our
program, i think there are no memory leak(or it will
panic in same time) and other fatal error.
Here is my dump information:
