[irda-users] [2.6.20-rt8] "Neighbour table overflow."

[Guennadi L. <gl...@ds...>]

Hi

After fixing the irda spinlock init bug, here's the next one I've run 
into: after a long irnet/ppp test with a periodic disturbance, whereby the 
ppp connection is broken and restored every ~20 secnds, I've got this from 
the kernel:

user.warn kernel: Neighbour table overflow.

and the system cannot build any new outgoing network connections - ppp or 
ethernet. I can connect from outside, but from the system produces:

# ping 192.168.1.1
connect: No buffer space available

where "new" connections is to new hosts. To known hosts connections can be 
further built. And, here's another one:

# ping 192.168.1.5
PING 192.168.1.5 (192.168.1.5) 56(84) bytes of data.

any ideas?...
