Cisco VPN Concentrator - lack of log data

I am evaluating FA4 build 4030 and have a strange issue. My Cisco 3005 VPN Concentrator has been configured as specified (Syslog server address, port specified to match the syslog server on FA4, Severities 1-5 being sent to Syslog).

However the only events that seem to get noticed/reported on in FA4 in my login to the VPN Concentrator console/gui. No other IPSEC/VPN communication gets logged. I have also enabled syslog to another device from the Cisco VPN I am getting a lot of information.

What happens to the majority of the log entries at the FA4 box. I have tried both "Original" and "Cisco IOS compatible" log formats. Still the only events logged and the only time the number of packets increase is when I logon to the VPN Concentrator console/gui.

BTW I am also logging from a CheckPoint device with major issues, so I am sure that the FA4 application is working.

Any ideas?
