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 -- Before posting, please read the FAQ: http://ecos.sourceware.org/fom/ecos and search the list archive: http://ecos.sourceware.org/ml/ecos-discuss
