Network Issue on OMSA start

[Olivier BONHOMME]

Hello,

I just upgraded to the last OMSA version 6.5.0 on my RHEL 5.6 uptodate 
and I have a very strange behaviour : When I start OMSA, the network 
stack crashes.

The behaviour I observed is that outgoing traffic is OK but not 
incoming. If I want the network back, I must down and up the interfaces.

Does anybody already had such an issue ?

Thanks for your answers

Regards,
