Hi,

Thank you for your reply.
I hope I solved my problem (I can't test for the moment, I'm at home). 
The cause was (I hope) a "misconfiguration" of some switches. 
Thursday-afternoon I needed to monitor a port on a switch for trafic. I 
saw a configuration I didn't see yet : Auto DoS. I believed this would 
prevent DoS attacks, so I enabled it, and on two other switches. It 
seems it's the opposite, it prevents some trafic, effectively creating a 
DoS.
I just googled, and it's a known problem of that switch type : HP 
ProCurve 1810G.

I reverted that, I'll have to see what's happening monday.

But your suggestions are noted for future troubleshooting. So, thanks again.
