2 x 3c509B-TPO
NetBSD-current with 'options GATEWAY'
I am getting a "panic: timeout table full" when my PC is
acting as a router, and there are large UDP transmits.
I am routing between ep0/ep1 with a SparcStation on each
subnet. Running the following command on the SparcLX panics
the NetBSD/i386 router almost immediately. (< 2seconds)
# ./ttcp -t -s -u address.of.sparc.2
(and './ttcp -r -s -u' on the sparc 2)
Using TCP does not trigger a panic. NFS mounts over UDP do
not either. It appears to be back-to-back UDP only.
Install 2 3c509s and use ttcp to test routing performance
with the above commands.
Unknown. Increasing maxusers to 64 did not help. The if_ep.c
timeout() seems to be at fault.
