our cisco asa had some trouble today.
Don't know if it's because of more ipv6 interfaces and more traffic (we 
are using native IPv6 since a few weeks).

Every minute the whole network would have a short break (maybe because 
the dispatcher process on the asa took too long) and we have got 60.000+ 
connections open (normally ~5.000).
Really bad for nfs/cifs :(


After switching to the standby failover asa everything worked fine.. 
Don't know what really the reason was but I'm sure many will blame it on 
IPv6...
