That's fairly high. Sure you didn't starve the CPU at some point ? Some parts of a network driver may require deferred cleanup work. If that work starts getting postponed too much, you may run out of buffers sooner or later. You should be able to load your system with a significant amount of additional work with lower priority (cpu 0% idle and lots of I/O). > Network card is Freescale P2020 On-Chip MAC.

I would suggest that you instrument it to check the state of the buffers etc. when the problem occurs. BTW please include the mailing list when responding.
