periodic reappearance of login prompt

[David Clark]

The basics of my setup are as follows:
- MPC8245 PowerPC on a custom board
- Linux Kernel 2.6.14
- BusyBox 1.00
- uClibc
 
I'm having a weird problem in which the login prompt reappears
automatically and periodically.  There are two scenarios that are very
repeatable and consistent.
 
1.  If I do not login, the login prompt reappears after 80 seconds.
2.  If I do login in, the login prompt reappears after 40 second.
 
This repeats forever.  I have heard of issues involving segmentation
faults in which busybox silently fails and all the user sees is a new
login prompt.  This could be a similar issue and obviously it is
happening in a function that is running on a timer.
 
Does anybody have any thought or suggestions?
What busybox functions, if any, run off a timer?
