I wasn't behind my server when it loss connection.
No way to contact him from my office, so went fast to my datacenter to
regain access (ok no remote control pdu on this machine and not
virtualised (1 of 3 old school survivors on my network), so hard
access to this hardware when problem)
So when arrived in my box, face to my server, wired my kvm screen and
so no way to get any network from my server.

But it was unsolved by my collegues. grrh, now it's too late to get
response less than waiting horribly for a potential new bug ...
Keeping the logs away from log rotate, will have to read and prepare
cups of cofee for this week end
