Hi, We have a Zope 2.6.2 server running on a Windows 2000 Server with 1.5GB of RAM running an application that connects to an SQL Server database. We have found that the Zope service (python.exe) continually builds up RAM usage until it finally crashes. After restarting the service it rapidly builds up to 20-50MB. Within a day or 2 it will reach 200MB and after a week or 2 it will reach a little over 1GB (often after or during a period of heavy usage) and will crash and have to be restarted. It never seems to go down - even during quiet times when no one is using the system it doesn't release any memory, the memory usage of the Python process just keeps climbing. Any ideas why this could be so? (The application uses external methods to create objects of classes and return them to be used in the ZPT) Tim Edwards Trainee Analyst Programmer Henry Walker Eltin Phone: 02 9887 6393 Email: tim.edwards@hwe.com.au
