network problem


I have a device using the MPC859T processor that has a small web server
running using the standard eCos web server. I have a status page that
auto-refreshes every 15 seconds and I am pinging the unit every second (Yes,
I have a customer that is actually doing this). I don't really know what
other network activity is occurring at the customer's site but my test lab
has Windows network chatter going on. After about 12 or so hours the web
stops responding and the unit can no longer be pinged. The FEC Ethernet
driver is receiving packets and is calling the eth_drv_dsr but the deliver
function is never called.

I have been tracking this down for some time and have noticed the
following...

1. The alarm thread in timeout.c is getting blocked when calling
splx_internal() just before the call to eth_drv_run_deliveries().
2. The current value of spl_state in sync.c is 4 (SPL_NET)

Any ideas why the network would not release the splx_mutex?
Any suggestion on how to further track this down?
I don't have a GDB interface on my platform. :(

Thanks in advance,
Rick Davis
