Hi,

I wonder if anyone can help us to get out of the problem we are
currently facing. We are using uCLinux Kernel version 2.4.19-uc1 and
uClibc 0.9.20 as library with mips-nommu architecture(Lexra
Processor). What happens is that when we plug our board in th network
slowly our memory is getting reduced. We are getting two types of
errors whose decriptions are pasted below. After these errors system
goes down:

Situation 1:
This situation we got when we left the device connected to network for
long time. We got unaligned memory access which in turn causes
"badvaddr" to be printed.
