We are running Exchange 2003. About once a day, sometime more, the exchange store seems to go a little crazy to the point that disk access becomes very slow. It is not taxing any other resources, cpu and memory usage remain low, but actual disk activity is very high. I have verified this using diskmon.exe and store.exe is repeatedly performing write operations on the priv database. At first we though it was normal, this is a 10 user organization. There was an unused server and we decided to move exchange to it so that it could have it's own server and not slow down the main file server. Well now exchange is just slowing down the new server the same way it did on the old server. I have scoured the event logs and nothing appears to be wrong. Are there any suggestions to find out why exchange is doing this?
