[omniORB] Blockage on a heavy network

I have noticed a strange thing too: All is working fine if the PC and the 
etrax are plugged on a Cisco3524XL switch, but when I replace it by a cheap 
Dlink DES-1024D switch, the blocage occurs after less than 30 minutes 
(whether I use OmniORB 3.0.4 or 4.0.1) !!

Cheers,
DESCOMBES Thierry
