It similar to the behavior that I see. I don't usually see this
with expect though. Possibly, this is because I use my own build
of expect linked tcl8.3.
I see this behavior quite consistently on my c3750 if I
1. Run the gcc libjava testsuite.
2. Usually, there a set of processes (e.g., Process_3) left running
after the testsuite ends. These processes are not defunct and
load the processor. I can kill all but the oldest thread.
3. Killing the oldest thread panics the kernel. Sometimes the system
reboots. However, the system often hangs doing endless panics.
I suspect a timing issue as the c3750 is the fastest processor that
I test on. I don't see as many problems with the libjava testsuite
on slower hardware. At one time, I thought this might be a 32 versus
64-bit issue, but I see the same problems running a 64-bit kernel.
