[PVE-User] Recurring crashes after cluster upgrade from 5 to 6

[Hervé Ballans]

Dear all,

Since we upgraded to these versions (15 days ago), we don't encounter 
anymore the problem :)

We are still waiting a few more days to be sure of stability but looks 
good !

Anyway, just for my education, is there someone here who can explain 
shortly what was the problem (unicast management ?) or who have a good 
link regarding this "behavior" ? Thanks !

Cheers,
rv
