Well... I finally got it to happen on my development system, by putting it on the corporate LAN and letting it get bombarded by all those stupid broadcast messages.
The state of the driver was that the ring buffer tail pointer ended up with a NULL pbuf pointer, so it was stalled. And my pbuf resources were exhausted before the head pointer wrote all the way around the ring again, so it stalled when the pbufs ran out. So... turned out to be my driver, looks like in my case. Just needed to add some protection to avoid overrunning the ring buffer (I'm not sure it was purely an overrun; it may have been an unprotected area in the buffer read routine that needed protection from interrupts as well.) Gonna let it run over the weekend with the fixes and we'll see how it looks on Monday. -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Taranowski, Thomas (SWCOE) Sent: Friday, February 29, 2008 5:22 PM To: Mailing list for lwIP users Subject: RE: [lwip-users] Problem with long term running of lwIP.
