Preventing excessive email notification from server.

I am using HP SIM 7.3. I have a lot of servers connected and from time to time one of servers is generating huge amount of traps - for example last time i get 78 messages (SNMP) Server Redundancy Lost: Important SIM events.
These messages are forwarded to first line support and they are very angry when they get 78 SMS messages :)
I waste a lot of time searching for solution to prevent repeatedly send the same notification in the same time - maybe you will be able to help me ?
Thanks in advance.
