TunnelStateData Connection error

[Nicolás Valera <nvalera@xxxxxxxxx>]

Hi,

i get the following error in the cache.log on heavy traffic

2012/02/29 14:09:02| TunnelStateData::Connection::error: FD 302: 
read/write failure: (110) Connection timed out
2012/02/29 14:21:47| TunnelStateData::Connection::error: FD 282: 
read/write failure: (113) No route to host

Does anybody see the same behaviour?
I checked Google but didn't find anything

Thanks in advance!
