It is used for the "Extreme cache detail" ZMI page but can also be used differently (e.g. from an "External Methode" or via the "ZServer Monitor Server" interactively).
I've never known how to use the monitor server. Are there examples or documentation anywhere?
Yes, I have seen monitor server documentation -- but I forgot where. But it is very easy: You need to enable the monitor server. This entails its configuration and the creation of an emergency user (with plain text password). Then, you use the "ZServer.medusa.monitor_client[_win32]" to connect to your monitor server. You will be asked for authentication and use the emercency user and its password. After successful authentication, you have a Python interpreter prompt inside your Zope process. You use "from Zope2 import app; app=app()" and you have an "app" object -- similar to "bin/zopectl debug".
... Yes, but it's a bad failure mode. Slow-but-functional is better than throwing MemoryErrors in my book... (especially as a trashed cache resolves itself, whereas MemoryErrors always seem to require a restart...)
How preferences differ.... But after you have found the culprit (and removed it), there will be no more "MemoryError"s :-) -- Dieter
