I regularly have errors (kernel: dst cache overflow) and crash of a

	I assume IP_ROUTE_MULTIPATH_CACHED is disabled. Do you have
BRIDGE_NETFILTER enabled/used?
- IP_ROUTE_MULTIPATH_CACHED is not set
- BRIDGE_NETFILTER is set, but I do not use it.

	ok, then can you try the attached patch, it solves dst cache
problem for another user, may be it will help you too. This patch can
be used with or without routes patches. It makes sure we don't leak
dst entry in bridge-netfilter. If the patch does not help let me know
and we can add some printks to catch the problem.

Hi,

Thank you for your answer, as your patch comes from the kernel 2.6.20, I installed this version of the kernel with the patch (routes-2.6.20-14.diff).

That made a little more than one week that I supervise and it cache is well cleaned regularly. All seems to be good. :o)

Regards.
