Teamsite File Corruption

System

My company has experienced major Teamsite file corruptions recently (We just launched our project two months ago.). The version we are using is 5.52 sp1. Interwoven support has given possible causes of file corruptions, such as improper shutdown. Unfortunately, those causes do not really help us. We are still experiencing file corruption, even though everything is working fine. Does file corruption happen very often with Teamsite? Is there any practical way to prevent this from happening?
