tinc connections fallout

[Bart Friederichs]

Hi,

Our VPN runs okay for some time, and every now and then one of the links (we
have three hosts connected redundantly) just falls out with no reason. In the
syslog I get several (strange?) messages:

Feb 14 09:56:02 ophar tinc.pirnet[2816]: 212.187.121.188 port 655: Connection
	timed out  
Feb 14 09:56:02 ophar tinc.pirnet[2816]: Could not set up a meta
	connection to 212.187.121.188

	failed to connect to other, will retry in 900 seconds

Feb 14 09:58:22 ophar tinc.pirnet[2816]: Bogus data received from unknown

Could someone give some commentary on those messages?

TIA
