Sometimes, you cannot login TestArchitect. It hangs after you click on Login button on Login Dialog. This issue may happen when your project is really big (50k+ test results).
Each TestArchitect repository maintains a log, known as the hit list, of database transactions (items checked in, items checked out, etc.) over time. Normally, the repository server writes to this log in real time for every transaction, in an operation referred to as "hit list clearance". As the log grows, this constant maintenance can cause performance to take a hit.
Option 1: You can schedule hit list clearance periodically to avoid the issue
