[Zope] Zope memory problem

[Tim Edwards]

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)
