I have Netgear VPN Firewall Router FVS124G.
It has a VPN link to 2 other routers.
For about a week ago now the vpn log shows:

TUE JUN 17 15:25:50 2008  INFO :: Sending phase-I notify of type R_U_THERE_ACK
TUE JUN 17 15:25:51 2008  INFO :: received NOTIFY PAYLOAD of notify type R_U_THERE

TUE JUN 17 15:26:12 2008  INFO :: Sending phase-I notify of type R_U_THERE_ACK

It won't stop and users have been reporting slower connection speeds.

How can I tell what is causing this?

Any help would be appreciated.

Those are DPD (Dead Peer Detection) messages from the remote end (a keepalive if you will).  This is a normal and good thing for IPSEC tunnels as it allows the tunnel to be torn down if communication is lost between the client and server.  I doubt this is the cause of your slow performance issues.  You may be able to disable the DPD functionality if you want to rule it out (maybe not on the Netgear though).
