Is this in a PPro machine? The folks at U of Utah are having a similar problem. Accessing the shared memory on ports on the second set of 16 ports sometimes generates a PCI parity error. The problem doesn't happen for them (or for me) on P5 systems, although there was one report from someone of this happening about once a day under heavy use on a P5 system. It appears to be some sort of hardware/timing problem related to the Cyclades PCI interface. If you haven't already, you might try using cytest.exe to change the card to be mapped in high memory rather than 640K-1M and see if this makes any difference. -DG David Greenman Core-team/Principal Architect, The FreeBSD Project
