>Description:

Set up: this is a HP 712/60 with 32MB RAM. It is a diskless setup with
root swap and usr as exports to the machine. Due to current keyboard problems it is only used to log in via ssh.

after several hours of uptime with low usage the machine started to 
print the following to the console,:

iee0: iee_intr: receive ring buffer overrun
receive error rfd status: 0x0000 rfd count: 0x0000

repeated over and over together with another status count that was increasing, but I failed to copy verbatimly from the screen. Parallel the machine became unreachable over the network, it did no longer respond to ping, xterms hung, etc.
>How-To-Repeat:

1- as said in "Full Description"

2- driving high utilisation e.g. start compiling a kernel or a package the machine will be unreachable over the network after about 10 to 15min. These lock-ups though did not print to the console, as above. In these ocasions the network "just" hung.

 Some update:
 I got 128MB for my hp712 recently. As a side effect the hang-up
 in the Network as described in this PR does not happen any longer.

 The machine has now enough physical
 RAM to not use any of the swap e.g. while compiling a package
 in a nfs-mounted export which includes some network-traffic doing
 so.

 Thus it seams that the bug described is somehow related to using swap.

 Feedback to
  (iee0: iee_intr: receive ring buffer overrun)

 with NetBSD head-20070421  I could not repeat
 above bug, thus I'd consider this one solved.
