I am having some problems with the performance and stabilty of Filemaker server 7. It is in a medium sized buisness network enviornment and there are multiple users across a local network and vpn. I use remote desktop to manage and monitor the server. In the past few days I have had a high number of crashes (4 in 1 day) and numerous corrupted files. I have installed the upgrades, tried to optimize larger files, and saved compressed copies but the stability dosen't seem to have improved. I cant seem to pinpoint any circumstances that would cause the server to be so unstable. I was hoping to get some helpful hints or user experiences...

Sounds like your database files are hopelessly corrupted. I would find a previous backup that is not corrupted, import your data into this as a clone and try again.
