The array is constant once the milter is started. To refresh the array I restart the milter every hour Do I have to still take care of deadlocks ? Now I think this was due to some network issue. The ethernet links were on half-duplex for this machine. I have forced a full duplex and now the problem is apparently disappeared. ( fingers crossed )
