OpManager losing some daily statistics

OpManager losing some daily statistics

Hi,
 
Not sure if this is the right place to post this. I have installed OpManager 8, (build 8051) and setup a complete monitoring system of our hosting centre (this is running on Windows Server 2003, IIS 6.0). Now everything will work fine for a few days, all the details are shown on our dashboard and the iphone client keeps up to date with alarms etc. Then all of a sudden, all the Disk Utilisation figures stop appearing on the dashboard and the iphone client can no longer see any devices (from the device category selection). If you search for the devices they can be found but when you select them the CPU, Memory and Disk are shown as NA in all three.
 
The only way it appears to recover from this is to restart the OpManager service in the services snap-in and as a result of this a days statistics (i think the most recent days) go missing.
 
Any help would be much appreciated.
 
Andy
